Subject: mmc: core: Annotate cmd_hdr as __le32

From: Jiri Slaby <jslaby@suse.cz>

commit 3f2d26643595973e835e8356ea90c7c15cb1b0f1 upstream.

Commit f68381a70bb2 (mmc: block: fix packed command header endianness)
correctly fixed endianness handling of packed_cmd_hdr in
mmc_blk_packed_hdr_wrq_prep.

But now, sparse complains about incorrect types:
drivers/mmc/card/block.c:1613:27: sparse: incorrect type in assignment (different base types)
drivers/mmc/card/block.c:1613:27:    expected unsigned int [unsigned] [usertype] <noident>
drivers/mmc/card/block.c:1613:27:    got restricted __le32 [usertype] <noident>
...

So annotate cmd_hdr properly using __le32 to make everyone happy.
