cluster/afr: Undo pending xattrs only on the up bricks
Problem:
While doing conservative merge, even if a brick is down, it will reset
the pending xattr on that. When that brick comes up, as part of the
heal, it will consider this brick as the source and removes the entries
on the other bricks, which leads to data loss.
Fix:
Undo pending only for the bricks which are up.
