[PULL REQUEST] one more fix for md: destroy partitions when stopping an array.

[Neil Brown <neilb@suse.de>]

Just one more... :-)

    md: destroy partitions and notify udev when md array is stopped.
    
    md arrays are not currently destroyed when they are stopped - they
    remain in /sys/block.  Last time I tried this I tripped over locking
    too much.
    
    A consequence of this is that udev doesn't remove anything from /dev.
    This is rather ugly.
    
    As an interim measure until proper device removal can be achieved,
    make sure all partitions are removed using the BLKRRPART ioctl, and
    send a KOBJ_CHANGE when an md array is stopped.
