qemu_driver.c: do not redefine 'event' in qemuDomainDefineXMLFlags()

A bad merge while rebasing 74b2834333 caused the @event variable
to be defined twice, inside the 'cleanup' label, causing coverity
errors.

This code was originally moved outside of the label by commit
773c7c4361. Delete the unintended code in the 'cleanup'
label.
