        src/sys/dev/pci: if_wm.c

Log Message:
wm(4): if_flags and IFNET_LOCK audit

Don't touch if_flags without IFNET_LOCK:

- If only core lock is held, use sc_if_flags.
- If only txq lock is held, use txq_stopping.
  => Verified all paths guarantee !txq_stopping, so assert.
- Make sure sc_if_flags is updated on stop.
- Make wm_init fail once we enter wm_detach.
- Sprinkle assertions.
