connect: output the same error msg on both code paths

[mback2k]

A failed verifyconnect on CURL_CSELECT_OUT printed the
error message "Connection failed", but the same failure
on CURL_CSELECT_ERR did not. This commit brings it in line.

I am also not sure if the two "Connection failed" infof statements are really needed, since there is this in case of an error:

curl/lib/connect.c

Lines 954 to 958 in d746ff1

	Curl_printable_address(conn->tempaddr[i], ipaddress,
	sizeof(ipaddress));
	infof(data, "connect to %s port %ld failed: %s\n",
	ipaddress, conn->port,
	Curl_strerror(error, buffer, sizeof(buffer)));

I agree. Those two infof() error message should probably be removed in preference of the one with more details.

[mback2k]

@bagder are you sure? The more detailed verbose message is hidden in case CURL_DISABLE_VERBOSE_STRINGS is defined.

[bagder]

Yes, as CURL_DISABLE_VERBOSE_STRINGS also converts infof() into a noop.
