Fix gss_set_cred_option cred creation with no name.

When creating a cred in the mechglue with gss_acquire_cred, the
mechanism is allowed to return no name from gss_inquire_cred. But in
the analagous operation in gss_set_cred_option, that would result in
an error from gss_display_name. Make the call to gss_display_name
conditional on the mechanism name being set. Reported by Andrew
Bartlett.
