rtlwifi: merge ips,lps spinlocks into one mutex
With previous patch "rtlwifi: use work for lps" we can now use mutex for protecting ps mode changing critical sections. This fixes running system with interrupts disabled for long time. Merge ips_lock and lps_lock as they seems to protect the same data structures (accessed in rtl_ps_set_rf_state() function).
