rbd: drop redefining map option warning

For example:

    # ./rbd map -o share,noshare foo
    rbd: warning: redefining map option share: 'share' -> 'noshare'
    /dev/rbd0

mount(8) doesn't do this and it's a bit silly to begin with.  Drop this
in preparation for adding rbd default map options config option.
