[Intel-gfx] The behavior of i915_wait_request() after calling i915_gem_suspend_request()

[Zhi Wang]

Hi Chris and Joonas:
     Thanks for the discussion in the IRC for the suspend/resume request 
APIs. I just a bit curious about the behavior of i915_wait_request() 
after a caller suspend an i915 request. Will the caller of 
i915_wait_request() be woken up at this time? or not? This behavior 
decides how we are going to use those APIs. :)

Thanks again for the discussion and efforts. :)

Thanks,
Zhi.
