Maxime Bélair 1c8a839442 apparmor: propagate -ENOMEM correctly in unpack_table 
Currently, if the `kvzalloc` in `unpack_table` fails, it returns NULL.
This is masked by `aa_dfa_unpack` which interprets NULL as a -EPROTO,
leading to confusing error messages in `apparmor_parser` [1].

The fixed behavior correctly propagates -ENOMEM on allocation failure.
