qemu: blockcopy: Don't remove existing disk mirror info

When creating a new disk mirror the new struct is stored in a separate
variable until everything went well. The removed hunk would actually
remove existing mirror information for example when the api would be run
if a mirror still exists.

(cherry picked from commit 02b364e186d487f54ed410c01af042f23e812d42)

This fixes a regression introduced in commit ff5f30b.
