gpu: nvgpu: gv11b: fix engine context preempt completion
CTX_STATUS_SWITCH: Engine save hasn't started yet, continue to poll
CTX_STATUS_INVALID: The engine context has switched off. The
preemption step for this engine is complete.
CTX_STATUS_VALID or CTX_STATUS_CTXSW_SAVE: check the ID field:
* If ID matches the TSG for the context being torn down, the engine
reset procedure can be performed, or SW can continue
waiting for preempt to finish if id is not being torn down.
* If ID does NOT match, the context isn't running on the engine.
CTX_STATUS_LOAD: check the NEXT_ID field:
* If NEXT_ID matches the TSG of the context being torn down, the engine
is loading the context and reset can be performed
immediately or after a delay to allow the context a chance to load and
be saved off, or sw can continue waiting for preempt to finish if id
is not being torn down.
* If NEXT_ID does not match the TSG ID or CHID then the context is no
longer on the engine.
SW may alternatively wait for the CTX_STATUS to reach INVALID, but this
may take longer if an unrelated context is currently on the engine or
being switched to.
