svn commit: r335597 - head/sbin/newfs

[Eitan Adler]

Author: eadler
Date: Sun Jun 24 05:40:42 2018
New Revision: 335597
URL: https://svnweb.freebsd.org/changeset/base/335597

Log:
  newfs: clean up warnings
  
  - remove param: unused since r95357.
  - correct definition of usage
  - add explicit fallthrough notice. The existing one doesn't work with
  our selection of "implicit-fallthrough" strictness.
  
  This results in WARNS=6 building on amd64, but not other arches
