[e1] Correctly initialize the e1link (Andreas Eversberg) 

During bootstrap of BS11, the e1links are initialized. This must also be
done when BS11 is already bootstrapped (when restarting OpenBSC). It is
required to correctly multiplex the audio traffic between channels.
Without it, all time slots refer to card 0, slot 0, subslot 0, which
causes crashes when handling TRAU frames..
