Patrick McHardy d0856009db [PATCH] crypto: fix null encryption/compression
null_encrypt() needs to copy the data in case src and dst are disjunct,
null_compress() needs to copy the data in any case as far as I can tell.  I
joined compress/decompress and encrypt/decrypt to avoid duplicating code.

Without this patch ESP null_enc packets look like this:
