md: fix v1.x metadata update when a disk is missing.
If an array with 1.x metadata is assembled with the last disk missing, md doesn't properly record the fact that the disk was missing. This is unlikely to cause a real problem as the event count will be different to the count on the missing disk so it won't be included in the array. However it could still cause confusion. So make sure we clear all the relevant slots, not just the early ones. Signed-off-by: NeilBrown <neilb@suse.de>
