Fix the possible wrong last_auto_fpga_lbt_th saving:

Browse Source 
1. Remove the last_auto_fpga_lbt_th saving from sdrctl set reg command. Otherwise, repeated sdrctl set reg will save wrong value into last_auto_fpga_lbt_th
2. The last_auto_fpga_lbt_th is only set in ad9361_rf_set_channel, which is called at least once by Linux after NIC is up
