[2/9] netconsole: Remove bogus check

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.
