[PATCH] virtio-mem: silence a static checker warning

[Dan Carpenter]

Smatch complains that "rc" can be uninitialized if we hit the "break;"
statement on the first iteration through the loop.  I suspect that this
can't happen in real life, but returning a zero literal is cleaner and
silence the static checker warning.
