Remove inessential/unwanted statements

[Balwinder S Dheeman]

Hi,

In LTE_fdd_enodeb/src/LTE_fdd_enb_gw.cc, I saw a lot of inessential/unwanted assignment statements:

started   = false;

I'm not sure, the optimizer can/will remove these, hence I'm submitting a patch for your kind review and adaption, if seems apropriate to you.
