mmc: hsq: Fix data stomping during mmc recovery
The block device uses multiple queues to access emmc. There will be up to 3
requests in the hsq of the host. The current code will check whether there
is a request doing recovery before entering the queue, but it will not check
whether there is a request when the lock is issued. The request is in recovery
mode. If there is a request in recovery, then a read and write request is
initiated at this time, and the conflict between the request and the recovery
request will cause the data to be trampled.
