[Intel-gfx] [PATCH i-g-t] i915/gem_concurrent_blit: Do not try to idle while submitting in parallel

[Chris Wilson]

If we try to idle while another thread is submitting, we will be forced
to wait until that other thread is finished -- effectively serialising
the parallel workloads, defeating said purpose.
