features/changelog: Don't modify 'pargfid' in 'resolve_pargfid_to_path'
Backport of http://review.gluster.org/#/c/13845/
If 'changelog' is enabled and 'changelog.capture-del-path' option is on
it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by
caller.  'changelog_unlink' calls this routine directly with
'loc->pargfid' resulting it being modified and point to root instead of
actual pargfid. This is a nasty bug and could cause the deletion of
entry on root directory instead on actual parent when 'loc->path' is
not present.  Hence this fix to make 'pargfid' a const pointer and
'resolve_pargfid' to work on copy of pargfid.
Glusterfind session creation enables these options by default to
capture deleted entry path in changelog.
Thanks Pranith for root causing this.
