drm/amdgpu/sdma: Fix executing duplicate commands after recovery on SDMA v4.4.2
SDMA v4.4.2 had a custom recovery implementation that
tried to keep ring contents and restore the rptr after
an SDMA soft reset. Later it was changed to use the
more common amdgpu_sdma_reset_engine() implementation.
Currently, SDMA v4.4.2 may execute some commands twice
after a recovery:
1. From the old ring buffer contents at the restored rptr
2. From the contents restored by amdgpu_sdma_reset_engine()
that calls the ring reset helper functions.
Fix that by removing the code that restores rptr.
This is not needed anymore because amdgpu_sdma_reset_engine()
already saves and restores the contents of both the SDMA gfx
and paging rings, so there is no need to do anything extra.
