lockdep: Change mark_held_locks() to check hlock->check instead of lockdep_no_validate
The __lockdep_no_validate check in mark_held_locks() adds the subtle
and (afaics) unnecessary difference between no-validate and check==0.
And this looks even more inconsistent because __lock_acquire() skips
mark_irqflags()->mark_lock() if !check.
Change mark_held_locks() to check hlock->check instead.
