dm zoned: Silence a static checker warning

My static checker complains about this line from dmz_get_zoned_device()

	aligned_capacity = dev->capacity & ~(blk_queue_zone_sectors(q) - 1);

The problem is that "aligned_capacity" and "dev->capacity" are sector_t
type (which is a u64 under most configs) but blk_queue_zone_sectors(q)
returns a u32 so the higher 32 bits in aligned_capacity are cleared to
zero.  This patch adds a cast to address the issue.
