UHDDevice: catch LookupError/IndexError in set{Rx,Tx}Antenna()

Currently configuring 3 channels in multi-ARFCN mode makes the
process crash during the Rx/Tx antenna configuration due to
uncaught UHD specific LookupError/IndexError exceptions:

  terminate called after throwing an instance of 'uhd::index_error'
    what():  LookupError: IndexError: multi_usrp:
      TX channel 2 out of range for configured TX frontends

Let's catch them and terminate gracefully.
