Michal Privoznik b0579ed900 storage: resize vol against real allocated size 
Currently, 'vol-resize --allocate' allocates new space at the
vol->capacity offset. But the vol->capacity is not necessarily the same
as vol->allocation. For instance:.

	[root@localhost ~]# virsh vol-list --pool tmp-pool --details
	 Name      Path                   Type  Capacity  Allocation
	-------------------------------------------------------------
	 tmp-vol  /root/tmp-pool/tmp-vol  file  1.00 GiB  1.00 GiB

	[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 2G

	[root@localhost ~]# virsh vol-list --pool tmp-pool --details
	 Name      Path                   Type  Capacity  Allocation
	-------------------------------------------------------------
	 tmp-vol  /root/tmp-pool/tmp-vol  file  2.00 GiB  1.00 GiB

So, if we want to allocate more bytes, so the file is say 3G big, the
real allocated size is 2G actually:

	[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate

	[root@localhost ~]# virsh vol-list --pool tmp-pool --details
	 Name      Path                   Type  Capacity  Allocation
	-------------------------------------------------------------
	 tmp-vol  /root/tmp-pool/tmp-vol  file  3.00 GiB  2.00 GiB

This commit uses the correct vol->allocation instead of incorrect
vol->capacity, so the output of the commands above looks like this:

	[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate

	[root@localhost ~]# virsh vol-list --pool tmp-pool --details
	 Name      Path                   Type  Capacity  Allocation
	-------------------------------------------------------------
	 tmp-vol  /root/tmp-pool/tmp-vol  file  3.00 GiB  3.00 GiB

Moreover, if the '--alocate' flag was used, we must update the
vol->allocation member in storageVolResize API too, not just
vol->capacity.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
