Do not try to release virtio serial addresses
Do not try to release virtio serial addresses

Return 0 instead of 1, so that qemuDomainAttachChrDevice does not
assume the address neeeds to be released on error.

No functional change, since qemuDomainReleaseDeviceAddress has been a noop
for virtio serial addresses since the address cache was removed
in commit 19a148b.
