qcacld-3.0: Avoid switch channel during preauth

qcacld-2.0 to qcacld-3.0 propagation

Currently data tx is suspended and later checked for preauth
in limProcessChannelSwitchTimeout. This can result in a condition
that data tx to be always in suspend case if roaming triggers at
the same time.

Fix is to add a check for preauth during channel switch.
