Now that AES-CMAC has a library API, convert ksmbd_sign_smb3_pdu() to use it instead of a "cmac(aes)" crypto_shash. The result is simpler and faster code. With the library there's no need to dynamically allocate memory, no need to handle errors, and the AES-CMAC code is accessed directly without inefficient indirect calls and other unnecessary API overhead.
