[PATCH] md sync_page_io bio leak

I accidentally introduced a leak in there, because the end_io function
doesn't do a bio_put() like most others. Fortunately it's not critical,
as it only happens on the md super block read. So just drop the initial
bio_get(), since it's sync we can just bio_put() safely at the end after
it has completed.
