mac80211: Fix incorrect num_sta_ps decrement in __sta_info_destroy

Browse source

When WLAN_STA_PS_DRIVER is set by ieee80211_sta_block_awake the
num_sta_ps counter is not incremented. Hence, we shouldn't decrement
it in __sta_info_destroy if only WLAN_STA_PS_DRIVER is set. This
could result in an incorrect num_sta_ps counter leading to strange side
effects with associated powersaving clients.

Fix this by only decrementing num_sta_ps when WLAN_STA_PS_STA was set
before.
