    protocol/client: give preference to loc->gfid over inode->gfid

    Backport of review.gluster.org/#/c/12233/

    There are xlators which perform fops even before inode gets linked. Because
of this loc.gfid is preferred at the time of inodelk/entrylk but by the time
unlock can happen, inode could be linked with a different gfid than the one in
loc.gfid (because of the way dht was giving preference) Due to this unlock goes
on a different inode than the one we sent inodelk on, which leads to hang.

    Credits to Pranith for the fix.
