drm/amdgpu: add new flag to AMDGPU_CTX_QUERY2

OpenGL EXT_robustness extension expects the driver to stop reporting
GUILTY_CONTEXT_RESET when the reset has completed and the GPU is ready
to accept submission again.

This commit adds a AMDGPU_CTX_QUERY2_FLAGS_RESET_IN_PROGRESS flag,
that let the UMD know that the reset is still not finished.
