bts: When one link drops.. check what needs to be dropped
In case a BTS is dropped, iterate over the list of BTS and check
if a dependency is now missing and then drop the BTS. This check
could lead to check of 256*256 checks (e.g. all BTS on each other
in the chain and the master is being dropped). The performance
aspect of it doesn't matter for our usecase. We expect to have
pairs of BTS right now.
