[PATCH] BUG/MINOR: tcp: avoid closing fd when socket failed in tcp_bind_listener

[William Dauchy]

we were trying to close file descriptor even when `socket` call was
failing.
this should fix github issue #499

this should be backported to all versions >= v1.8

Fixes: 153659f1ae69a1 ("MINOR: tcp: When binding socket, attempt to
reuse one from the old proc.")
