trafgen: gracefully handle ENOBUFS on tx ring teardown

pull_and_flush_tx_ring_wait() in the exit path of xmit_fastpath_or_die()
might return with errno ENOBUFS (due to the other CPU's processes
concurrent access) but will eventually suceed. Thus retry
pull_and_flush_tx_ring_wait() as in the main loop of
xmit_fastpath_or_die().

Fixes #175
