libceph: separate CRC calculation from byte swapping
Calculate CRC in a separate step from rearranging the byte order of the result, to improve clarity and readability. Use offsetof() to determine the number of bytes to include in the CRC calculation. In read_partial_message(), switch which value gets byte-swapped, since the just-computed CRC is already likely to be in a register.
