commit 2fdea258fde036a87d3396ec9c0ef66f10768530 upstream.
To be able to generate shared descriptors for AEAD, the authentication size
needs to be known. However, there is no imposed order of calling .setkey,
.setauthsize callbacks.
Thus, in case authentication size is not known at .setkey time, defer it
until .setauthsize is called.
The authsize != 0 check was incorrectly removed when converting the driver
to the new AEAD interface.
