Fix the possible wrong last_auto_fpga_lbt_th saving:
...
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

Fix the issue of iGent env related big ping delay:
...
1. The issue only happens at zcu102 side, when it is tested as AP together with zedboard
2. The issue does not happen when zcu102 is client and zedboard is AP
3. The issue (most likely) does not happen in places other than iGent (like Pablo home)
4. Sometimes it does happen at my home when I test zcu102 as AP together with COTS WiFi
5. Indeed seems like the environment related. Guess some quick small packets in the environment quickly flush/round-up/mess-up the rx dma cyclic buffer, and the rx interrupt internal static variable target_buf_idx_old loses track of the background automatic rx dma cyclic buffer
6. The fix is for all board types (zcu102, zedboard, 7035, etc)
7. The driver compiling make_all.sh script generates USE_NEW_RX_INTERRUPT macro to pre_def.h to enable the new code (while keeping the old code). You can use the script as before.
8. The logic of the fix is that exhaustive search all the rx dma cyclic buffer in rx interrupt to get packet to Linux in the first place.

Fix the state unsync issue between rx interrupt and mac80211. When the issue happens, only a new packet incoming could trigger an old rx packet going to mac80211 rx. And this new fix also could work with the original xilinx dma driver. Our slightly modified xilinx dma driver is not needed anymore.
