nvme: Increase block size variable size to 32-bit

dagomez137 · keithbusch · commit bdbfcd5f6caa · 2023-06-12T10:36:59.000-07:00
Increase block size variable size to 32-bit unsigned to be able to
support block devices larger than 32k (starting from 64 KiB).

Physical and logical block size already support unsigned 32-bit.
