Freeing pending transfers on shutdown is done in openOCD
and on libusb side. This created concurrency in freeing
memory and segmentation faults:
https://github.com/libusb/libusb/issues/1627
Bug is reproduced better if many targets are laucnhed.
Bug was reproduced with CMSIS-DAP on targets:
cyw20829, psoc4, stm32l5 if launching multiple times.
Proposed working fix: if some transfers pending/in-flight
on 'shutdown' then apply libusb_handle_events_timeout_completed()
to make transfer complete. In all cases transfer completed
due to tests.
