Teach urndis to handle some REMOTE_NDIS_INDICATE_STATUS_MSG. If the status
is reasonable, don't tell userland we got an error. Stops spurious EIO.
>From openbsd.

Fix bug, remove {0,0} because we switched to usb_lookup().

s/no free/no freelist entry/ in a debug message.

fix a lock hang reported by sc.dying in PR#54495.

remove locking in usbnet_tick().  assume that all locking
needs are handled inside usbnet_tick_task(), which runs in
the usbtask thread.  ensure that usbnet private is valid
before using it.

also check NULL private pointer in usbnet_isdying().
all the other cases should never happen.

don't try to set dying when we haven't usbnet_attach()d yet.

- use CALLARGS vs CALLED for better usbhist
- turn off usbnetdebug default
- log for all entry/exit points of usbnet_pipe_intr()
- in usbnet_start_locked() track whether any packet has been
  transmitted for setting the timer.  avoids spurious
  "watchdog timeouts"
- in usbnet_stop() use callout_halt() vs callout_halt, and
  also stop the usb task.  fixes crash of usbtask after the
  phy has detached.
- add a little more defensive checking in the tick task, and
  add some high-log-level logs.
- in usbnet_detach() move the call to usbnet_stop_ifp() above
  the calls to callout/usbtask stopping.
- set ec_mii and unp_pri to NULL when freeing their data

normalise an error message.

document usbnet_private locking.  minor knf.
