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.
Fixes: 70978208ec91 ("dm zoned: metadata version 2")
