Gabriel reported the lockdep splat below while investigating something
different.

Explanation for the splat is in the function comment above
del_timer_sync().

I can reproduce it as well and it's clearly broken.

Agree, the disable logic is broken. The below isn't super pretty, but it
should do the trick for 4.10.

Cures the splat. Is that a new 4.10 'feature'? That wbt stuff has been
merged a few releases ago.

Thanks,
