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.
