qcacld-3.0: Disable the scheduler thread in the init error path

During the module initialization the scheduler thread and the
init thread run in parallel if there is a failure in the error
path, the scheduler thread is not aware and still sending
the messages to firmware resulting in system instability.

Disable the scheduler as soon as there is an error in the init path.
