mmc: core: Fix WRITE_ZEROES CQE handling
commit028822b714
upstream. 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:f7b6fc3273
