J. Nick Koston 20884d5844 Use empty() instead of empty_relaxed() for wifi_loop_ fast path ...

GCC on Xtensa emits memw for relaxed atomic loads too, so the
savings from relaxed vs acquire are only 2 memw (~4 cycles) — not
worth the weaker correctness guarantees. The real optimization is
the early return that skips get_and_reset_dropped_count() and the
pop() loop entirely.
