dm: fix to_sector() for 32bit
A dm-raid array with devices larger than 4GB won't assemble on
a 32 bit host since _check_data_dev_sectors() was added in 4.16.
This is because to_sector() treats its argument as an "unsigned long"
which is 32bits (4GB) on a 32bit host. Using "unsigned long long"
is more correct.
Kernels as early as 4.2 can have other problems due to to_sector()
being used on the size of a device.
Fixes: 0cf4503174c1 ("dm raid: add support for the MD RAID0 personality")
