crypto: algapi - use separate dst and src operands for __crypto_xor()
In preparation of introducing crypto_xor_cpy(), which will use separate operands for input and output, modify the __crypto_xor() implementation, which it will share with the existing crypto_xor(), which provides the actual functionality when not using the inline version.
