qcacld-3.0: Use correct hw mode switch reason

Currently the driver uses the reason code
POLICY_MGR_UPDATE_REASON_CHANNEL_SWITCH for
chanenl switch for P2P-CLI which is same
reason code used for hw mode change in case
of SAP, so after the hw mode is changed the
VDEV-SM does call the callback of SAP CSA
also.

Fix is to use a different reason code for
SAP CSA.
