Add 'force' flag to *hot_remove_disk().
In rare circumstances, the short period that *hot_remove_disk()
waits isn't long enough to IO to complete. This particularly happens
when a device is failing and many retries are still happening.
We don't want to increase the normal wait time for "mdadm --remove"
as that might be use just to test if a device is active or not, and a
delay would be problematic.
So allow "--force" to mean that mdadm should try extra hard for a
--remove to complete, waiting up to 5 seconds.
Note that this patch fixes a comment which claim the previous
wait time was half a second, where it was really 50msec.
