[PATCH] md 21 of 22 - Improve handling of MD super blocks
1/ don't free the rdev->sb on an error -- it might be
accessed again later. Just wait for the device to be
exported.
2/ Change md_update_sb to __md_update_sb and have it
clear the sb_dirty flag.
New md_update_sb locks the device and calls __md_update_sb
if sb_dirty. This avoids any possbile races around
updating the superblock
