[PATCH] mmc: fix null pointer use in mmc_blk_remove_req

[franck.jullien@gmail.com]

From: Franck Jullien <franck.jullien@gmail.com>

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, sadly, mmc_cleanup_queue set
mq->card to NULL.

This patch moves the card pointer assignment before
mmc_cleanup_queue.
