cli: fix crash in arbiter keyword parsing

Backport of http://review.gluster.org/#/c/14738/

A negative case like `gluster volume create volname arbiter 3 /bricks{1..3}`
must not crash. 'arbiter' keyword is valid only for (3 way) replica volumes.

The .t that is added will crash and create a core *without* the fix when
run but will still pass all TESTs. Since the regression framework fails
the .t if it creates a core,  we can consider it a valid test 'that
fails without the fix'.
