crypto: cmac - return -EINVAL if block size is unsupported

cmac_create() previously returned 0 if a cipher with a block size other than 8 or 16 bytes was specified. It should return -EINVAL instead. Granted, this doesn't actually change any behavior because cryptomgr currently ignores any return value other than -EAGAIN from template ->create() functions.
