mmc: core: Initialize mmc_blk_ioc_data
commit0cdfe5b0bf
upstream. Commit4d0c8d0aef
("mmc: core: Use mrq.sbc in close-ended ffu") adds flags uint to struct mmc_blk_ioc_data, but it does not get initialized for RPMB ioctls which now fails. Let's fix this by always initializing the struct and flags to zero. Fixes:4d0c8d0aef
