    sbin/hammer: Make volume count test optional for blkdevs based commands
    
    This is basically for feature enhancement of hammer strip command
    in the next commit. No functional change by this commit.
    
    Some blkdevs based commands need to be able to handle broken volume
    headers by omitting volume verification (to certain extent). It has
    been that way for the volume header contents, but not for volume
    count as well as checking existence of root volume.
