[PATCH] integrity: don't throw an error immediately when failed to add a cert to the .machine keyring

Currently when the kernel fails to add a cert to the .machine keyring,
it will throw an error immediately in the function integrity_add_key.

Since the kernel will try adding to the .platform keyring next or throw
an error (in the caller of integrity_add_key i.e. add_to_machine_keyring),
so there is no need to throw an error immediately in integrity_add_key.
