[PATCH v2 03/14] drm/v3d: Use inline lock for dma fence initialization

[Maíra Canal <mcanal@igalia.com>]

Since commit 1f32f310a13c ("dma-buf: inline spinlock for fence protection
v5"), dma_fence_init() accepts a NULL external lock and will fall back to
an inline spinlock embedded in the fence itself. The embedded spinlock
allows the decoupling the lock and the fence lifetime.

Pass NULL so each v3d fence uses its own inline lock. This will allow
queue_lock to use spin_(un)lock() in all its uses instead of
spin_(un)lock_irqsave().
