drm/amdgpu: Fix the ring buffer size for queue VM flush

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2071621

[ Upstream commit fe93b0927bc58cb1d64230f45744e527d9d8482c ]

Here are the corrections needed for the queue ring buffer size
calculation for the following cases:
- Remove the KIQ VM flush ring usage.
- Add the invalidate TLBs packet for gfx10 and gfx11 queue.
- There's no VM flush and PFP sync, so remove the gfx9 real
  ring and compute ring buffer usage.
