qcacld-3.0: Do not clear session id

No valid channel found when DUT as P2P GO and radar signal detected,
stop ap and then up layer start ap again, session id of adapter
changed to invalid since session id of sap context is invalid and
passed to adapter in hdd_hostapd_sap_event_cb with event
eSAP_START_BSS_EVENT. So, do not clear session id of sap context for
stopping ap due to invalid channel case.
