packed should always exist without calling its cleanup function explicitly. Moreover, we have use it when preparing packed list. So I don't believe we should ever fall into this check again when doing mmc_blk_packed_hdr_wrq_prep or mmc_blk_end_packed_req,etc. And the code of mmc_blk_end_packed_req is trying to use packed before checking it which makes it quite weird. This patch is trying to remove these two checks and move it to the mmc_blk_prep_packed_list. If we find packed is null, then we should never use MMC_BLK_PACKED_CMD. By doing this, we could fall back to non-packed request if finding null packed, though it's impossible theoretically. After removing these two BUG_ONs, we also remove all other similar checks within the routine of mmc_blk_issue_rw_rq which checks the error handling of packed request.
