mmc: block: Retry commands in CQE error recovery

stable inclusion
from stable-v6.6.5
commit 3e04ce4b2572e6288456757a1a4b077be0efc87b
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8N21P

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3e04ce4b2572e6288456757a1a4b077be0efc87b



--------------------------------

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.
