media/rc: Send sync space information on the lirc device

commit a8f29e89f2b54fbf2c52be341f149bc195b63a8b upstream.

Userspace expects to see a long space before the first pulse is sent on
the lirc device.  Currently, if a long time has passed and a new packet
is started, the lirc codec just returns and doesn't send anything.  This
makes lircd ignore many perfectly valid signals unless they are sent in
quick sucession.  When a reset event is delivered, we cannot know
anything about the duration of the space.  But it should be safe to
assume it has been a long time and we just set the duration to maximum.
