drm/amdgpu: move userq fence wait out of signalling section
The eviction fence suspend worker waits for every pending userq fence
from inside a dma_fence_begin_signalling() critical section. Waiting on
another DMA fence while responsible for signalling one violates the
cross-driver fence contract and is reported by lockdep as a
dma_fence_map dependency.
Move the wait before dma_fence_begin_signalling(). Keep userq_mutex held
so queue lifetime remains stable while inspecting last_fence.
