        src/sys/dev/pci: if_wm.c

Log Message:
- rnd_add_*() call must be serialized. Unserialized accesses broke the
  sc->rnd_source structure and caused off by one in kern_rndq.c's
  rnd_add_data_ts(). This problem was found by kUBSan. Make krndsource_t's
  data per queue-pair and call rnd_add_uint32() in wm_txrxintr_msix(). One of
  the reason why rnd_add_uint32() calls were moved from wm_{tx,rx}eof() is that
  rnd(9) manual page says "To allow the system to gather the timing information
  accurately, this call should be placed within the actual hardware interrupt
  service routine."
- Pass a better value to rnd_add_uint32() in wm_intr_legacy().

XXX pullup-8.
