[patch 19/28] netconsole: Remove bogus check

[akpm@linux-foundation.org]

From: Satyam Sharma <satyam@infradead.org>

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.
