Liu Yuan fca23f0ad2 sheepdog: show error message for halt status 
Sheepdog (neither quorum nor unsafe mode) will refuse to serve IO requests when
number of alive nodes is less than that of copies specified by users. This will
return 0x19 to QEMU client which currently doesn't recognize it.

This patch adds an error description when QEMU client receives it, other than
plainly printing 'Invalid error code'
