[libvirt] [PATCH 3/8] virstoragefile: Resolve Coverity DEADCODE

[John Ferlan]

Coverity complains that the condition "size + 1 == 0" cannot happen.
It's already been determined that offset+size is not larger than
buf_size (and buf_size is smaller than UINT_MAX); and also that
offset+size didn't overflow.

So just remove the check
