[libvirt-php][PATCH 2/5] src: Don't leak @uuid in libvirt_nwfilter_get_uuid_string

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

VIRT_RETURN_STRING() does immediate return. Therefore,
efree(uuid) is never called and thus leaked. Moreover, there's no
reason for dynamically allocated uuid buffer (in contrast to our
misuse of large static buffers).
