failures in benchmark_radio for bladeRF 2.0 micro

Issue Description

Refer to https://github.com/srsran/srsRAN_4G/issues/1247 I have been suspecting Radio interface as issue since I see very flaky and intermittent attach with bladeRF 2.0 micro XA4 with srsenb and srsue.

I thought of benchmarking and ran benchmark_radio program present in srsRAN_4G/build/lib/src/radio/test

First I did it for baldeRF 2.0 micro XA4. I see 2 number of overflows.

With same host machine, I just swapped bladerf with Ettus usrp B210 board and I don't see any overflows. Does it mean that bladeRF 2.0 micro is having some issue interfacing with srsRAN_4G? Please share your own experiences or insights.
