[NET] netconsole: Remove bogus check
Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>.
The (!np.dev) check in write_msg() is bogus (always false), because: np.dev is
set by netpoll_setup(), which is called by init_netconsole() before
register_console(), so write_msg() cannot be triggered unless netpoll_setup()
successfully set np.dev. Also np.dev cannot go away from under us, because
netpoll_setup() grabs us reference on it. So let's remove the bogus check.
