[UPF] Avoid crash if no default subnet configured (#1624) 

In that case, ogs_pfcp_ue_ip_alloc() will fail with  the error message
"CHECK CONFIGURATION: Cannot find subnet [...]" and the assert will make
upf crash.
That's not desirable, let's keep it running and simply reject the
request. The error log is big enoguh to find out.
