Modified Files:
        src/sys/dev/usb: usbnet.c

Log Message:
- 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
