md: Fix regression with raid1 arrays without persistent metadata.
A RAID1 which has no persistent metadata, whether internal or external, will hang on the first write. This is caused by commit 070dc6dd7103b6b3f7e4d46e754354a5c15f366e In that case, MD_CHANGE_PENDING never gets cleared. So during md_update_sb, is neither persistent or external, clear MD_CHANGE_PENDING. This is suitable for 2.6.36-stable. Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org
