NeilBrown ab904d6346 [PATCH] md: fix bitmap/read_sb_page so that it handles errors properly.
read_sb_page() assumed that if sync_page_io fails, the device would be marked
faultly.  However it isn't.  So in the face of error, read_sb_page would loop
forever.

Redo the logic so that this cannot happen.
