dm error: add discard support
Add io_err_io_hints() and set discard limits so that the zero target
advertises support for discards.
The error target will return -EIO for discards.
This is useful when the user combines dm-error with other
discard-supporting targets in the same table; without dm-error
support, discards would be disabled for the whole combined device.
