Subject: [PATCH 38/74] protocol/server: fix the comparision logic in case of
 subdir mount

without the fix, the stat entry on a file would return inode==1 for
many files, in case of subdir mount

This happened with the confusion of return value of 'gf_uuid_compare()',
it is more like strcmp, instead of a gf_boolean return value, and hence
resulted in the bug.

Also fixes the bz1501714
