btrfs: fix uninitialized ret in ref-verify
Coverity caught a case where we could return with a uninitialized value
in ret in process_leaf. This is actually pretty likely because we could
very easily run into a block group item key and have a garbage value in
ret and think there was an errror. Fix this by initializing ret to 0.
