wlan: Fix roaming latency caused by cfg80211_get_station

While roaming is going on, Framework initiate
cfg80211_get_station to collect station statistic,
Which in turn block the call or wait for time-out.
This can be overcome by avoiding cfg80211_get_station
if it is triggered in between the Roaming to reduce
the roaming latency.
