dm zoned: Avoid 64-bit division error in dmz_fixup_devices
When building arm32 allyesconfig: ld.lld: error: undefined symbol: __aeabi_uldivmod >>> referenced by dm-zoned-target.c >>> md/dm-zoned-target.o:(dmz_ctr) in archive drivers/built-in.a dmz_fixup_devices uses DIV_ROUND_UP with variables of type sector_t. As such, it should be using DIV_ROUND_UP_SECTOR_T, which handles this automatically.
