drm/amdkfd: Handle deallocated VPGRs in gfx11+ trap handler

A wavefront may deallocate its VGPRs at the end of a program while
waiting for memory transactions to complete. If it subsequently
receives a context save exception it will be unable to save,
since this requires VGPRs. In this case the trap handler should
terminate the wavefront.

Fixes intermittent VM faults under context switching load.

V2: Use S_ENDPGM instead of S_ENDPGM_SAVED for performance counters
