  Add locking and make xe(4) MPSAFE:
  - Add a mutex to protect the softc and device hardware.
  - Use a callout rather than a callout_handle for the media timer.
  - Use a dedicated timer for managing the tx watchdog rather than if_timer.
  - Fix some resource leaks if xe_attach() fails.
  - Shutdown the device before detaching the driver.
  - Setup the interrupt handler after ether_ifattach().
