    RBD: Fix error on disconnect

    On the RBD driver, when doing a disconnect call inside a container, when
    the "rbd_common" package is installed on the host, we can get a "No such
    file or directory" error if the udev rule from the host removes the
    symlink before we do.

    This error is caused by the rm command returning 1 for different type of
    errors, so we'll now use -f to ensure we don't fail if the file is
    missing, which is what we intended before when passing the
    check_exit_code parameter to the execute call.
