md:raid1: fix a dead loop when read from a WriteMostly disk
commit 816b0acf3deb6d6be5d0519b286fdd4bafade905 upstream.
If first_bad == this_sector when we get the WriteMostly disk
in read_balance(), valid disk will be returned with zero
max_sectors. It'll lead to a dead loop in make_request(), and
OOM will happen because of endless allocation of struct bio.
Since we can't get data from this disk in this case, so
continue for another disk.
