Do some cleanup of the SDT code:
- remove the sdt cdev, it's not used.
- don't bother keeping a list of probes for each provider, it's not
  needed.
- invoke sdt_load and sdt_unload from the module handler instead of
  registering separate SYSINITs.
- stay within 80 columns.
- check for errors from dtrace_unregister().
