    md: revert the recent addition of a call to the BLKRRPART ioctl. · cb3ac42b

    It turns out that it is only safe to call blkdev_ioctl when the device
    is actually open (as ->bd_disk is set to NULL on last close).  And it
    is quite possible for do_md_stop to be called when the device is not
    open.  So discard the call to blkdev_ioctl(BLKRRPART) which was
    added in
       commit 934d9c23
    
    It is just as easy to call this ioctl from userspace when needed (on
    mdadm -S) so leave it out of the kernel
