Fcnt for uplink should not be incremented for retransmission about lorawan

[DvdMgr]

Thanks for pointing this out.

Actually, frame counters have not been implemented/tested so far, as their behavior does not impact the outcome of simulations we are interested in. If you want to implement them correctly also at the NetworkServer, please submit a pull request and I'll look into it! Otherwise, I can just remove the line you pointed out to fix this.

Expected Behavior

Same as title.
According to lorawan spec 1.0.3 (https://lora-alliance.org/sites/default/files/2018-07/lorawan1.0.3.pdf), section **4.3.1.5 ** (ln 520-530) seems to suggest retransmitted frame's Fcnt should not be incremented. Similar idea is expressed in sect 4.3.1.1 ln 443-444.

Actual Behavior

end-device-lorawan-mac.cc line 291: m_currentFCnt++;
