[PATCH] md: better handling for read error in raid1 during resync

Handling of read errors during resync is separate from handling of read errors
during normal IO in raid1.  A previous patch added support for read errors
during normal IO.  This one adds support for read errors during resync or
recovery.

The key differences are that we don't need to freeze the array, because the
normal handling of resync means that this part of the array will be idle
except for resync, and the read/overwrite/re-read is needed in a separate
piece of code.
