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.
