mmc: core: Fix NULL ptr crash from mmc_should_fail_request
commit e5723f95d6b493dd437f1199cacb41459713b32f upstream.
In case of CQHCI, mrq->cmd may be NULL for data requests (non DCMD).
In such case mmc_should_fail_request is directly dereferencing
mrq->cmd while cmd is NULL.
Fix this by checking for mrq->cmd pointer.
Fixes: 72a5af554df8 ("mmc: core: Add support for handling CQE requests")
