bsdinstall: Fix newfs bsddialog menu

[emaste]

Summary

The first 3 members of struct bsddialog_menuitem are:

                   const char *prefix;
                   bool on;
                   unsigned int depth;

The newfs dialog options in bsdinstall's partition tool had on and depth
swapped, so the defaults did not work.

Fixes: 50e244964e9b ("bsdinstall/partedit: Replace libdialog with libbsddialog")

Separately this should probably just be -F 32 without -c 1. I will look at that and post a patch after testing.
