FHI72: remove polling, fix memory leak

- FHI72 used polling to track the next slot. This is not necessary, a
  simple queue does the job and allows to save one core that was
  previously at 100%
- Remove a workaround to avoid a memory leak (fixes #812); allows to
  also run RFsim/USRP/otehr radios when compiling for FHI72
