drm/v3d: Remove dedicated fence_lock

Commit adefb2ccea1e ("drm/v3d: create a dedicated lock for dma fence")
split `fence_lock` from `queue_lock` because v3d_job_update_stats() was
taking `queue_lock` to protect `job->file_priv` during stats collection
in the IRQ handler. Using the same lock for both DMA fence signaling and
stats protection in a IRQ context caused issues on PREEMPT_RT.

Since then, the stats infrastructure has been reworked: v3d_stats is now
refcounted and jobs hold their own references to stats objects, so
v3d_job_update_stats() no longer takes `queue_lock` at all.

With the original reason for the split gone, merge `fence_lock` back
into `queue_lock` to simplify the locking scheme.
