ipa: Fix a memory leak when the RSL/OML is dropped 'early'

In case the BTS didn't get identified there will be a leaked
e1inp_line. Free the e1inp_line when the OML and RSL link is dropped.

This has been tested with:
   b connect: 'localhost'. b waitForBTSReady. b stop.

and:
   oml-rsl-connect-close/OMLRSLConnectClose.st
