use of the macro in sbin/mount*'s, by replacing:
mopts[] = {
MOPT_STDOPTS,
{ NULL }
}
With:
mopts[] = {
MOPT_STDOPTS,
MOPT_NULL
}
This change will help to reduce the situation that we don't explicitly
initialize "struct mntopt"'s. It should not contribute to any
functional/logical changes as far as I can tell.
