[libvirt] [PATCH 9/9] virstoragefile: Resolve Coverity DEADCODE
Coverity complains that the condition "size + 1 == 0" cannot happen.
Since 'size' is unsigned 32bit value set using virReadBufInt32BE.
Thus rather than + 1, it seems the comparison should be is it at
max now and if so, return the failure.
