crypto: blowfish - rename C-version to blowfish_generic
Rename blowfish to blowfish_generic so that assembler versions of blowfish cipher can autoload. Module alias 'blowfish' is added. Also fix checkpatch warnings. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
