If vm->def->cputune.nvcpupin is 0 in libxlDomainSetVcpuAffinities (as seems to be the case on arm) then the VIR_FREE after cleanup: would be operating on an uninitialised pointer in map.map. Fix this by using libxl_bitmap_init and libxl_bitmap_dispose in the appropriate places (like VIR_FREE, libxl_bitmap_dispose is also idempotent, so there is no double free on exit from the loop). libxl_bitmap_dispose is slightly preferable since it also sets map.size back to 0, avoiding a potential source of confusion. This fixes the crashes we've been seeing in the Xen automated tests on ARM. I had a glance at the handful of other users of libxl_bitmap and none of them looked to have a similar issue.

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.
