qcacld-3.0: Fix bad channel in cfg80211 get channel for SAP

The cfg80211 callback for get channel is returning invalid
channel in case of SAP as the check for is vdev associated
will return false for SAP mode.

Keep this check only for STA mode only so SAP can return
the valid channel in get_channel callback.
