Subject: posix: Fix unlink failing under specific condition

PROBLEM:
Files are undeletable when these three conditions are met:
1. File does not have trusted.pgfid.<gfid> xattr set.
   This won't be set when build-pgfid is off (default).
2. File has hardlink count > 1.
3. build-pgfid option is turned on.

FIX:
Allow unlink on files not having trusted.pgfid.<gfid> xattr.
