Subject: [PATCH RFC 31/33] md/raid*: Fix raid*_set_queue_limits()

queue_limits_cancel_update() must only be called if
queue_limits_start_update() is called first. Remove the
queue_limits_cancel_update() calls from the raid*_set_limits() functions
because there is no corresponding queue_limits_start_update() call.

Cc: Christoph Hellwig <hch@....de>
Fixes: c6e56cf6b2e7 ("block: move integrity information into queue_limits")
Signed-off-by: Bart Van Assche <bvanassche@....org>
