dm zoned: fix overflow when converting zone ID to sectors
A zone ID is a 32 bits unsigned int which can overflow when doing the
bit shifts in dmz_start_sect(). With a 256 MB zone size drive, the
overflow happens for a zone ID >= 8192.
Fix this by casting the zone ID to a sector_t before doing the bit
shift. While at it, similarly fix dmz_start_block().
