enb: remove usleep after sending RRC Connection Release to UE 

this cause a "dead-lock" with ZMQ because it made the stack
thread sleep for 50ms. With a sync-queue size of 1 (now the default
using ZMQ) the zmq-based radio to timeout. as a result
the rx/tx between UE and eNB stopped so the UE never reached
RRC Idle state.
