Mark Johnston 4bfb585351 Don't treat an error from g_mirror_clear_metadata() as fatal.
Such errors can occur as the result of a write error or because the disk
backing the mirror element was removed. They result in a generation ID bump
on all active elements of the mirror, so we can safely disconnect the mirror
component rather than destroy it.
