Small fixes to sis(4):

- Remove sis_unit and use device_printf() and if_printf() instead.
- Use callout_init_mtx() for the callout.
- Remove spls.
- Fix locking for ifmedia to happen in the ifmedia handlers rather than in
  sis_ioctl().
- Log an error message if we fail to allocate any resources.  Perform
  cleanup if we fail to allocate any resources so that we don't leave
  a mutex hanging around.
