afr: Unset dirty xattr after setting pending xattr during post-op
In AFR transaction, in the pre-op, the dirty xattr is set. In the
post-op, if the transaction fails on one of the bricks, then on the
healthy brick, the dirty xattr is unset and then the pending xattr (for
the brick that went down) is set in that order. If the brick crashes
after unsetting the dirty xattr, we have lost information about a
pending heal. Hence we need to reverse the order, i.e. set pending xattr
first followed by unsetting the dirty.
