Remove 500-b43-disable_qos_when_openfw.patch

This patch is incorrect. It leaves mac80211 and b43 in different states.
mac80211's hw->queues will be left at 4 (QoS enabled), while QoS will be disabled
inside of b43's queue handling.

There currently is no way to disable QoS after loading the firmware.

Buildroot should probably statically change the module parameter to QoS=0, if the
opensource firmware is built into the image.
