Convert queue_max_sectors_store to use queue_limits_commit_update to
check and updated the max_sectors limit and freeze the queue before
doing so to ensure we don't have request in flight while changing
the limits.

Note that this removes the previously held queue_lock that doesn't
protect against any other read or writer.
