Internal pointers in CCM, GCM and XTS contexts should either be
NULL or set to point to the appropriate key schedule. This needs

PR#2579
(cherry picked from commit 79e31a2842e10271581cbfdaae0145dd4bd35107)

Add patch originally accidentally omitted to allow CMAC to work with
EVP_PKEY APIs.

IN parameter.

Under the old docs, the only thing stated was "at most
EVP_PKEY_size(pkey) bytes will be written". It was kind of misleading
since it appears EVP_PKEY_size(pkey) WILL be written regardless of the
signature's buffer size.
