5.4-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 8155d1fa3a747baad5caff5f8303321d68ddd48c ]
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.
