qcacld-3.0: Fix null pointer dereference in wma_roam_synch_event_handler

In wma_roam_synch_event_handler, if vdev_id is out of bounds,
code is redirected to cleanup, where iface is dereferenced to
set the value of roam_synch_in_progress.
This will result in a NULL pointer dereference because iface
hasn't yet been set.
Since this function does not have logic to set
iface->roam_synch_in_progress to true then it does not need
"cleanup" logic to undo that. So, remove the cleanup logic.
