crypto: af_alg - Allow cbc(paes)

Commit 7524070f26d8 ("crypto: af_alg - Drop support for off-CPU cryptography")
breaks a special use case.  The cbc-paes-caam driver implements the
algorithm cbc(paes), it offers a way to use AES in CBC mode with key
material unknown to userspace.  Instead of an AES key a CAAM BLOB is
passed to the kernel.  So, this crypto operation cannot be
implemented in a userspace library and needs always help from the
kernel.

Explicitly allow this use case.
