qcacld-3.0: Remove tSirAutoShutdownEvtParams usage

Currently when an auto-shutdown timer event is handled by WMA it
allocates a tSirAutoShutdownEvtParams struct which is then passed as
the payload of a eWNI_SME_AUTO_SHUTDOWN_IND message. However when this
message is processed by SME the payload is ignored since the callback
to HDD does not require it. Therefore it is pointless for WMA to
allocate and fill a payload which SME will ignore, so remove that
aspect of the auto-shutdown timer event handling.
