ceph_argparse: kill _daemon versions of argparse calls

Commit c76bbc2e6df1, which introduced _daemon versions of some of the
argparse calls, also changed the behaviour of non-_daemon versions.
The change resulted in incorrect error messages, e.g.

  $ ./rbd create b0 --size
  rbd: extraneous parameter --size

instead of what should have been

  $ ./rbd create b0 --size
  Option --size requires an argument.

The users of _daemon versions were added in commit be801f6c506d and
removed in commit f26bd55e57f1, so just kill the _daemon versions and
restore the old behaviour.  (This effectively reverts commit
c76bbc2e6df1.)
