[PATCH 3/9] hostap: Add missing annotations for prism2_bss_list_proc_start() and prism2_bss_list_proc_stop

[Jules Irenge]

Sparse reports warnings at prism2_bss_list_proc_start() and prism2_bss_list_proc_stop()

warning: context imbalance in prism2_wds_proc_stop() - unexpected unlock
warning: context imbalance in prism2_bss_list_proc_start() - wrong count at exit

The root cause is the missing annotations at prism2_bss_list_proc_start()

Add the missing __acquires(&local->lock) annotation
Add the missing __releases(&local->lock) annotation
