drm/i915: Ignore a hung GPU when flushing the framebuffer prior to a switch If the gpu is hung, then whatever was inside the render cache is lost and there is little point waiting for it. Or complaining if we see an EIO or EAGAIN instead. So, if the GPU is indeed in its death throes when we need to rewrite the registers for a new framebuffer, just ignore the error and proceed with the update.
