[ Upstream commit 24149412dfc71f7f4a54868702e9145e396263d3 ]

Fix up on mes process context flush to prevent non-mes devices from
spamming error messages or running into undefined behaviour during
process termination.

Fixes: bd33bb1409b4 ("drm/amdkfd: fix mes set shader debugger process management")
