BUG/MINOR: peers: fix error reporting of "bind" lines

In case the str2listener() parser reports a generic error with no message
when parsing the argument of a "bind" statement in a "peers" section, the
reported error indicates an invalid address on the empty arg. This has
existed since 2.0 with commit 355b2033e ("MINOR: cfgparse: SSL/TLS binding
in "peers" sections."), so this must be backported till 2.0.
