Ravishankar N 93c850dd2a afr: propagate correct errno for fop failures in arbiter
Problem:
If quorum is not met in fop cbk, arbiter sends an ENOTCONN error to the
upper xlators. In a VM workload with sharding enabled, this was leading
to the VM pausing when replace-brick was performed as described in the BZ.

Fix:
Move the fop cbk arbitration logic to afr_handle_quorum() because in
normal replica volumes, that is the function that has the quorum and
errno checks in the fop cbk path before doing a post-op.

Thanks to Pranith for suggesting this approach.
