Subject: [PATCH] Do not test skip_name_resolve if skip_networking is ON

MySQL name resolution only applies to TCP/IP connections ( see lines 504 and 599 of mysql-server/sql/sql_connect.cc ).  Thus there is no reason to test, or suggest, setting skip_name_resolve if skip_networking exists and is turned on.
