mmc: fix null pointer use in mmc_blk_remove_req
commit 8efb83a2f8518a6ffcc074177f8d659c5165ef37 upstream.
A previous commit (fdfa20c1631210d0) reordered the shutdown sequence
in mmc_blk_remove_req. However, mmc_cleanup_queue is now called before
we get the card pointer, and mmc_cleanup_queue sets mq->card to NULL.
This patch moves the card pointer assignment before mmc_cleanup_queue.
