cipher: Correctly propagate AEAD failures
Some pre-4.9 kernels have an AEAD bug that makes recvmsg() return an
incorrect value that does not include the AAD length. This could cause
an erroneous successful return from l_aead_cipher_{en,de}crypt() if
ad_len was longer than the expected output. operate_cipher() now returns
the number of bytes copied to the 'out' buffer, and the AEAD functions
only succeed if the expected number of bytes were copied.
