gfapi: Update loc->inode accordingly in 'glfs_loc_link'
In case if the inode already exits in the cache, inode_link returns the pointer to the exiting one instead of using loc->inode. This will result in issues if that invalid inodei(loc->inode) is referenced further. Fixed the same. This is backport of the below fix - http://review.gluster.org/#/c/11572/ BUG: 1241666 Change-Id: I1a89932397f7d2b70d619eeaf862c0a5d7f6b91c Signed-off-by: Soumya Koduri <skoduri@redhat.com> Reviewed-on: http://review.gluster.org/11572 Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> Reviewed-on: http://review.gluster.org/11606 Tested-by: Gluster Build System <jenkins@build.gluster.com>
