staging: rtl8192e: Remove unsupported mode IW_MODE_MASTER 

Tasklet irq_rx_tasklet is scheduled when hw is receiving frames. Function
_rtl92e_irq_rx_tasklet() is then called which calls then
_rtl92e_rx_normal(). In _rtl92e_rx_normal() all frames are processed by
rtllib_rx(). When ieee->iw_mode is IW_MODE_MASTER the function returns
0. The calling function then calls: dev_kfree_skb_any() which clears the
skb. So the driver clears all packets received in this mode. Remove dead
code in mode IW_MODE_MASTER.
