X-Git-Tag: frr-3.0-branchpoint~29^2~5

lib: prefix2str initialises incoming buffer in case erroneous EVPN pfx

In the case, evpn prefix is requested to be transformed into string, and
if the evpn prefix is not an evpn route type 5 entry, then the prefix is
returning an initialised string that mentions the vpn prefix is unknown.
