drm/amdkfd: No need to suspend whole MES to evict process

Browse Source 
Each queue of the process is individually removed and there is not need
to suspend whole mes. Suspending mes stops kernel mode queues also
causing unnecessary timeouts when running mixed work loads

Fixes: 079ae5118e ("drm/amdkfd: fix suspend/resume all calls in mes based eviction path")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4765
