BUG/MINOR: tcpcheck: conf parsing error when no port configured on server and first rule(s) is (are) COMMENT

A small configuration parsing error exists when no port is setup on the
server IP:port statement and the server's parameter 'port' is not set
and if the first tcp-check rule is a comment, like in the example below:

  backend b
   option tcp-check
   tcp-check comment blah
   tcp-check connect 8444
   server s 127.0.0.1 check

In such case, an ALERT is improperly returned, despite this
configuration is valid and works.

The new code move the pointer to the first tcp-check rule which isn't a
comment before checking the presence of the port.

backport status: 1.6 and above
