------------------------------------------------------
Subject: md: set desc_nr correctly for version-1 superblocks
From: NeilBrown <neilb@xxxxxxx>
This has to be done in ->load_super, not ->validate_super
Without this, hot-adding devices to an array doesn't always
work right - though there is a work around in mdadm-2.5.2 to
make this less of an issue.
