    sys/vfs/hammer: Ask before reblocking on volume-del
    
    hammer volume-del finishes instantly if the volume doesn't need
    reblocking, but it could take long depending on how much of the
    big-blocks within the volume is used.
    
    This commit makes hammer volume-del ask y/n whether to start
    reblocking or not if the volume wasn't empty. Using force option
    (-F) makes it reblock without asking.
    
    Also note that reblocking doesn't guarantee anything on removing
    a volume from filesystem. It just tries to move data to other
    volume(s) so the volume may become empty. Thus users should have
    choice.
    
     # hammer volume-del /dev/da2 /HAMMER
     /dev/da2 is not empty, do you want to reblock /dev/da2? [y/n]

     hammer volume-del ioctl: Directory not empty
