    Remove unnecessary close_device_and_disk()
    
    1) lp_disk is not used and assigned NULL so doesn't need closing.
    2) lp_device is already ped_device_open()ed and ped_device_close()d
    within the above while loop.  lp_device will be set to NULL when the
    while loop ends so this doesn't need closing either.  Hence
    close_device_and_disk() is always passed with two NULL pointers and is a
    no operation so can be removed.
