net: linkmode: make linkmode_test_bit() take const pointer 

linkmode_test_bit() does not modify the address; test_bit() is also
declared const volatile for the same reason. There's no need for
linkmode_test_bit() to be any different, and allows implementation of
helpers that take a const linkmode pointer.
