mmc: core: Fix WRITE_ZEROES CQE handling
WRITE_ZEROES requests use TRIM, so mark them as needing to be issued
synchronously even when a CQE is being used. Without this,
mmc_blk_mq_issue_rq() triggers a WARN_ON_ONCE() and fails the request
since we don't have any handling for issuing this asynchronously.
Fixes: f7b6fc327327 ("mmc: core: Support zeroout using TRIM for eMMC")
