mmc: block: Retry commands in CQE error recovery

commit 8155d1fa3a747baad5caff5f8303321d68ddd48c upstream.

It is important that MMC_CMDQ_TASK_MGMT command to discard the queue is
successful because otherwise a subsequent reset might fail to flush the
cache first.  Retry it and the previous STOP command.

Fixes: 72a5af554df8 ("mmc: core: Add support for handling CQE requests")
