Fix the bug in crc32_acle

On armv8-a platforms if --acle is enabled, zlib-ng will use crc32_acle
instead of the default crc32. However, in crc32_acle the __crc32b() is
used to calculate the crc result of two variables with types uint32_t
and uint64_t, which gives an error result.The correct function used
should be __crc32d().
