md: add error_handlers for raid0 and linear
After the commit 9631abdbf406c("md: Set MD_BROKEN for RAID1 and RAID10")
MD_BROKEN must be set if array is failed because state_store() checks it.
If it is set then -EBUSY is returned to userspace.
For raid0 and linear MD_BROKEN is not set by error_handler(). As a result
mdadm is unable to trigger clean-up actions. It is a regression.
This patch adds appropriate error_handler for raid0 and linear. The
error handler sets MD_BROKEN for this device.
