PD#145741: wifi: bcm: fix unable to enter deep suspend mode issue

for the wowlan (wake on wireless lan) function under Linux platfrom,
we have problem to configure it via wpa_supplicant as we do it at Android
platform. so here when it enter into suspend mode, we try to skip calling
cfg80211_leave_all() function at the wire core path.

since this modify the wifi core code, it will also affect other
wifi drivers (not only bcm wifi).
