commit 0cdfe5b0bf295c0dee97436a8ed13336933a0211 upstream.
Commit 4d0c8d0aef63 ("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.
