Subject: [PATCH] block: fix an warning of calling blk_rq_aligned()

2nd argument of blk_rq_aligned() has changed to 'unsigned long' by
previous commit 'block: fix an address space warning in blk-map.c'.
According to that change, its caller has to be modified. This also
removes address space warnings from sparse.
