block: fix an address space warning in blk-map.c
Change type of 2nd parameter of blk_rq_aligned() into unsigned long
and remove unnecessary casting. Now we can call it with 'uaddr'
instead of 'ubuf' in __blk_rq_map_user() so that it can remove
following warnings from sparse:
block/blk-map.c:57:31: warning: incorrect type in argument 2 (different address spaces)
block/blk-map.c:57:31: expected void *addr
block/blk-map.c:57:31: got void [noderef] <asn:1>*ubuf
However blk_rq_map_kern() needs one more local variable to handle it.
