veritysetup: minor renaming of functions

create_device() and create_disk() so far did very similar things, but
the name didn't give a hint what the difference was.

Hence let's rename them to create_special_device() and
create_veritytab_device() to make this more understandabe, as one
creates /proc/cmdline specified roothash=/usrhash= devices, and the
other one devices for items listed in /etc/veritytab.

No code changes besides renaming.
