sha2: Cast safe conversions to smaller integer types
Add a cast to lines converting "uint64_t" to "unsigned int" that are
known safe due to use of modulus with a small integer. This avoids
compiler warnings such as
conversion from 'cm_sha2_uint64_t' to 'unsigned int',
possible loss of data
from MSVC.
