Sylvain Munaut 7be04d6567 gmr1_rx: Don't count the borders when computing energy

Sylvain Munaut 0ddd957165 gmr1_rx: Don't try to low pass frequency correction 
Some receivers (like rtl-sdr) have fast changes in the frequency
error, especially while they're warming up and this prevents good
tracking.
