 Set display_value in krb5_gss_get_name_attribute

 A backwards conditional in r25358 caused krb5_gss_get_name_attribute
 not to set display_value on success.  Fix the sense of the
 conditional.

 We still don't quite correctly handle the cases where data_to_gss()
 fails, but those should be rare and the problem in those cases isn't
 severe, so it can be fixed separately.

 Also, value and display_value should probably be initialized to null
 buffers on failure, as is common with GSS interfaces.
