This fixes regression introduced in my recent ledtrig-netdev commit.
Events triggered by different interfaces were stopping timer so it
wasn't working for tx/rx mode.

The ppp0 interface is renamed after the connection is established. Due
to a missing NETDEV_REGISTER event, the ledtrig-netdev isn't aware of
the renamed interface and literally ignores the device
(no tx/rx indication, led isn't switched off with 'ifdown wan').

Previously switching to non-existing device (interface) could result in
leaving LED on.

We may just delete timer on every trigger update and then start it again
if needed. This will let us avoid both: races and locking in frequently
called timer callback.

Read/write lock was adding useless complexity, there wasn't any real
gain in case of this driver.
Also switch to _bh variants to avoid deadlocks.

All supported kernels require patching ledtrig-netdev in the same way,
so it's safe to just move these changes to the base version of this
driver. We needed these patches for some old kernels 2.6.36 and 3.11.
