qcacld-3.0: Remove sta adapter number check when add monitor iface

1. Permit to add monitor iface even wlan0 down per customer requirement.
2. Don't need check sta adapter number when add monitor iface, monitor
iface doesn't depend on sta adapter number, sta adapter num is different
for mlo/non-mlo, dual sta/single sta.
