sysfs: detect disks that are in the process of being removed

When removing a disk there is a window where the 'slot' attribute of
md/dev-$name will return -EBUSY to read attempts.  When this happens
look at the the 'block' link, if it is removed then we can be sure the
device has been removed, versus some other error.
