crypto: af_alg - whitelist mask and type
commit bb30b8848c85e18ca7e371d0a869e94b3e383bdf upstream.
The user space interface allows specifying the type and mask field used
to allocate the cipher. Only a subset of the possible flags are intended
for user space. Therefore, white-list the allowed flags.
In case the user space caller uses at least one non-allowed flag, EINVAL
is returned.
