staging: csr: remove unused define ALLOW_Q_PAUSE

#include <net/pkt_sched.h>

/* ALLOW_Q_PAUSE: Pre 2.6.28 kernels do not support multiple driver queues (required for QoS).

 * In order to support QoS in these kernels, multiple queues are implemented in the driver. But since

 * there is only a single queue in the kernel (leading to multiple queues in the driver) there is no possibility

 * of stopping a particular queue in the kernel. Stopping the single kernel queue leads to undesirable starvation

 * of driver queues. One of the proposals is to not stop the kernel queue but to prevent dequeuing from the

 * 'stopped' driver queue. Allow q pause is an experimental implementation of this scheme for pre 2.6.28 kernels.

 * When NOT defined, queues are paused locally in the driver and packets are dequeued for transmission only from the

 * unpaused queues. When Allow q pause is defined the kernel queue is stopped whenever any driver queue is paused.
