cluster/afr: Turn on eager-lock for fd DATA transactions

Problem:
With the present implementation, eager-lock is issued for
any fd fop. eager-lock is being transferred to metadata
transactions. But the lk-owner is set to local->fd address
only for DATA transactions, but for METADATA transactions
it is frame->root. Because of this unlock on the eager-lock fails
and rebalance hangs.

Fix:
Enable eager-lock for fd DATA transactions
