Ben Widawsky e20780439b drm/i915: Defer request freeing 
With context destruction, we always want to be able to tear down the
underlying address space. This is invoked on the last unreference to the
context which could happen before we've moved all objects to the
inactive list. To enable a clean tear down the address space, make sure
to process the request free lastly.

Without this change, we cannot guarantee to we don't still have active
objects in the VM.

As an example of a failing case:
CTX-A is created, count=1
CTX-A is used during execbuf
	does a context switch count = 2
	and add_request count = 3
CTX B runs, switches, CTX-A count = 2
CTX-A is destroyed, count = 1
retire requests is called
	free_request from CTX-A, count = 0 <--- free context with active object

As mentioned above, by doing the free request after processing the
active list, we can avoid this case.
