dm thin metadata: fix __udivdi3 undefined on 32-bit
commit 013ad043906b2befd4a9bfb06219ed9fedd92716 upstream.
sector_div() is only viable for use with sector_t.
dm_block_t is typedef'd to uint64_t -- so use div_u64() instead.
Fixes: 3ab918281 ("dm thin metadata: try to avoid ever aborting transactions")
