drm/amdkfd: only flush the validate MES contex
The following page fault was observed duringthe KFD process release.
In this particular error case, the HIP test (./MemcpyPerformance -h)
does not require the queue. As a result, the process_context_addr was
not assigned when the KFD process was released, ultimately leading to
this page fault during the execution of the function
kfd_process_dequeue_from_all_devices().
