replication: Remove workaround
Remove the workaround introduced in commit
6ecbc6c52672db5c13805735ca02784879ce8285
"replication: Avoid blk_make_empty() on read-only child".
It is not needed anymore since s->hidden_disk is guaranteed to be
writable when secondary_do_checkpoint() runs. Because replication_start(),
_do_checkpoint() and _stop() are only called by COLO migration code
and COLO-migration activates all disks via bdrv_invalidate_cache_all()
before it calls these functions.
