drm/amdgpu/gfx9: drop unnecessary 64-bit fence flag check in KIQ
Remove the BUG_ON(flags & AMDGPU_FENCE_FLAG_64BIT) assertion from
gfx_v9_0_ring_emit_fence_kiq(). The KIQ hardware supports 64-bit
fence writes; the 32-bit writeback address constraint is an
upper-layer convention, not a hardware limitation. The check serves
no purpose and should not be present.
Found by code inspection while investigating related BUG_ON
assertions in the GFX and compute ring emission paths.
