QNetworkInterface: fix warning of unused function 

That causes compilation error in developer build or when '-Werror'
command line argument is forced:

kernel/qnetworkinterface_unix.cpp:142:12: error: 'int getMtu(int, ifreq*)' defined but not used [-Werror=unused-function]
 static int getMtu(int socket, struct ifreq *req)
            ^
cc1plus: all warnings being treated as errors

So, mark 'getMtu()' as unused in the appropriate branches.
