usrp1: Remove uninitialized skipRx logic

There appears to have been some logic to operate a USRP1 in
transmit-only GSM mode.  This is achieved using the skipRx member
of the transceiver object.  However, there's nobody that ever
initializes it properly, and hence the feature is not possible to
use anyway.

I don't think this has any valid use case, so let's remove it.
