add header!

This patch adds the ability detect read failures during
recovery and flag the device as failed.
We add a call to fail_mirror() when 'read_err' is set
upon recovery completion. This sets the error_count
on the device. It maintains backwards compatibility
(does nothing) if the DM_RAID1_HANDLE_ERRORS flag is
not set during mirror device creation.
Using the same code put in place to handle write failures,
it ensures that the region is marked as 'not-in-sync'
and that this is reflected in the log.
