X.509: Fix crash caused by NULL pointer
On the following call path, `sig->pkey_algo` is not assigned
in asymmetric_key_verify_signature(), which causes runtime
crash in public_key_verify_signature().
keyctl_pkey_verify
asymmetric_key_verify_signature
verify_signature
public_key_verify_signature
This patch simply check this situation and fixes the crash
caused by NULL pointer.
