qcacld-3.0: Fix SAP start failure issue

Browse Source 
qcacld-2.0 to qcacld-3.0 propagation

At the time of driver load, sap session is opened as part of
hdd_init_ap_mode but in case of sap restart, sme_open_session
is called from sapFsm.
At the time of opening session, sme_open_session register
wlansap_roam_callback callback for connection status.
If this callback is not registered, HDD will not get connection
status and HDD will start cleanup after SAP connection timeout which
will result in SAP failure.
Need to register wlansap_roam_callback as part of sme_open_session
when session is not created as part of hdd_init_ap_mode.
