Self-heald: Fix inode leak

RCA:
There is an inode-leak because inode_link returns
linked inode by taking a reference. That needs to be
unreffed.

Fix:
Added the code to perform unrefs. In addition to that
updated the loc inode with the linked-inode because that is
the best practice. The code to update the input inode's
gfid can be removed later, its already removed in master.

Tests:
Checked that opendir comes with an loc with valid inode
Checked that re-opendir happens successfully. Tested index,
full self-heal work fine with the fix.
