qcacld-3.0: Disable auto ps timer on interface down

Auto ps timer is started as part of the interface up
but not disabled as part of the interface down.
Meanwhile if interface down happen hence sme session
get deleted. But if ps timer expire later then it try
to access invalid sme session and lead to abort.
As a part of fix, Disable auto ps timer on interface down.
