dma-buf: abstract fence locking v2
Add dma_fence_lock_irqsafe() and dma_fence_unlock_irqrestore() wrappers
and mechanically apply them everywhere.
Just a pre-requisite cleanup for a follow up patch.
v2: add some missing i915 bits, add abstraction for lockdep assertion as
well
v3: one more suggestion by Tvrtko
