    sbin/hammer: Make info command properly handle non HAMMER path
    
    This shouldn't be needed if i/f of libhammer were carefully designed,
    but this seems to be the only guaranteed way to detect non HAMMER path,
    and print a proper error message that makes sense for UFS, etc.
    
    -- before this commit
     # hammer info /boot
     hammer: libhammer_get_fsinfo     <--- ???
    
    -- with this commit
     # hammer info /boot
     hammer: /boot is probably not a HAMMER filesystem: Inappropriate ioctl for device
