TRX: prevent segfault upon phy init
Previously if multiply phy instances were configured but not used
osmo-bts-trx would segfault. Terminate with clear error message instead
so user can correct configuration. Example configuration which caused
problem:
...
phy 0
instance 0
instance 1
...
trx 0
phy 0 instance 0
Note the 2nd instance of phy 0 which is not used in trx later on.
