crypto: compress - remove crt_u.compress (struct compress_tfm)
crt_u.compress (struct compress_tfm) is pointless because its two
fields, ->cot_compress() and ->cot_decompress(), always point to
crypto_compress() and crypto_decompress().
Remove this pointless indirection, and just make crypto_comp_compress()
and crypto_comp_decompress() be direct calls to what used to be
crypto_compress() and crypto_decompress().
Also remove the unused function crypto_comp_cast().
