[PATCH] block: make blk_queue_zone_sectors() return sector_t type

[Dan Carpenter <dan.carpenter@oracle.com>]

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) but blk_queue_zone_sectors(q) returns a u32 so the
higher 32 bits in aligned_capacity are always cleared to zero.

Declaring blk_queue_zone_sectors() as a sector_t addresses this warning
and it feels intuitive based on the function name.  I updated
bdev_zone_sectors() as well just to be consistent.

Fixes: 114e025968b5 ("dm zoned: ignore last smaller runt zone")

Please review this one extra carefully.  I'm not positive it's correct.
