gpu: nvgpu: vgpu: abort the channel right after force reset it

Browse Source 
For gp10b and previous chips, RM server will issue fake mmu fault to
reset the channel. And the mmu fault event will be sent to vgpu client,
which will cause the client to abort the channel or tsg.
But on gv11b, RM server doesn't issue fake mmu fault any more. So I need
to abort it right after the force reset is finished.
