staging: brcm80211: removed locks around Mac80211 calls

A spinlock was acquired prior to calling the Mac80211 functions
ieee80211_wake_queues() and ieee80211_stop_queues() and Cfg80211 functions
wiphy_rfkill_set_hw_state() and wiphy_rfkill_start_polling().
This is not required and could even lead to instability. Therefore the locks
were removed.
