ieee802154: 6lowpan: change if lowpan dev is running
We don't need to check if the wpan interface is running because the
lowpan_rcv is the packet layer receive handler for the wpan interface.
Instead doing a check if wpan interface is running we should check if
the lowpan interface is running before starting 6lowpan adaptation layer.
