svn commit: r309351 - head/etc/defaults

Log:
  Revert the 'performance' setting to 'NONE' from C2. C2 has issues with
  USB in places, as well as having the potential for reducing
  performance. Since this is used even when powerd isn't enabled, these
  two problems can cause on servers. Supermicro X9 motherboards, for
  example, have problems with the virtual IPMI USB keyboards and mice
  attaching and detaching repeatedly. Since there are issues on some
  CPUs with C2, fail safe by defaulting to not altering it.
