blk-mq: remove redundant call to blk_freeze_queue_start in blk_mq_destroy_queue

Browse source

The calling relationship in blk_mq_destroy_queue() is as follows:

blk_mq_destroy_queue()
    ...
    -> blk_queue_start_drain()
        -> blk_freeze_queue_start()  <- called
        ...
    -> blk_freeze_queue()
        -> blk_freeze_queue_start()  <- called again
        -> blk_mq_freeze_queue_wait()
    ...

So there is a redundant call to blk_freeze_queue_start().

Replace blk_freeze_queue() with blk_mq_freeze_queue_wait() to avoid the
redundant call.
