[AMF] Ignore unexpected PATCH method in gmm_state_authentication (#4074)

Browse Source 
When the AMF receives a PATCH request for the registration API while in
the gmm_state_authentication state, it currently crashes because the
HTTP method is not handled. This appears to be a race condition.

To fix this, explicitly handle OGS_SBI_HTTP_METHOD_PATCH by ignoring the
message and logging an error, similar to the handling of other
unexpected SBI messages.
