block: fix data type casting for crypto payload offset
The crypto APIs report the offset of the data payload as an uint64_t
type, but the block driver is casting to size_t or ssize_t which will
potentially truncate.
Most of the block APIs use int64_t for offsets meanwhile, so even if
using uint64_t in the crypto block driver we are still at risk of
truncation.
Change the block crypto driver to use uint64_t, but add asserts that
the value is less than INT64_MAX.
