wl1271: Removed checking of PSM from handling BSS_LOST_EVENT
Change the driver to call ieee80211_beacon_loss function always when
BSS_LOST_EVENT is received. Reason for the change is that entering PSM
might fail before driver receives BSS_LOST_EVENT. In such case the
driver would disable PSM and the stack would not be notified about beacon
loss and connection loss detection would be delayed by tens of seconds.
