__rpc_gss_seccreate() doesn't set options_ret->major/minor_status on failure
As part of testing #15022, I created a utility to establish an RPCSEC_GSS context. It uses the optional argument to __rpc_gss_secreate() 'options_ret' so that it can print GSS error information if establishment fails for some reason. However, what it prints out is actually not that useful:
creating GSS ctx failed failed with errno 7 no GSS error info
It turns out that __rpc_gss_seccreate() doesn't actually set the major/minor_status arguments on failure. It would be nice if it did that.
Tested using the utility in #15022 to connect to a server where gssd is disabled.
