Hans Verkuil fe4526d99e media: cec: core: disable adapter in cec_devnode_unregister
Explicitly disable the CEC adapter in cec_devnode_unregister()

Usually this does not really do anything important, but for drivers
that use the CEC pin framework this is needed to properly stop the
hrtimer. Without this a crash would happen when such a driver is
unloaded with rmmod.
