While auditing the code I've noticed one place (the throttle ioctl) which does not yet wait for the reset handler to complete and doesn't properly decode the wedge state into -EAGAIN/-EIO. Fix this up by calling the right helpers. This might explain the oddball "my compositor just died in a successfull gpu reset" reports. Or maybe not, since current mesa doesn't use this ioctl to throttle command submission. The throttle ioctl doesn't take the struct_mutex, so to avoid busy-looping with -EAGAIN while a reset is in process, check for errors first and wait for the handler to complete if a reset is pending by calling i915_gem_wait_for_error.
