RFR: JDK-8312512: sspi.cpp gss_export_name avoid delete on NULL fullname

Mon Jul 24 08:00:53 UTC 2023

sspi.cpp contains the gss_export_name function, where at the end some cleanup is done by calling delete. However this should be done more careful, because the function get_full_name which is called in gss_export_name might return NULL, so we better avoid calling delete in this case.
