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().
