cfg80211: Do not disconnect on suspend
Qualcomm Technologies Inc vendor specific wlan driver (qcacld-3.0)
internally supports wow mode and is enabled by default.
Currently, cfg80211 subsystem and wpa_supplicant is not aware of
qcacld-3.0 internal support for wowlan, due to which wpa_supplicant
is issuing disconnect on suspend, resulting in wowlan failure.
To fix this, avoid disconnect on suspend.
