connect: Close open but unconnected socket in singleipconnect()
singleipconnect() could return the file descriptor of an open socket even though the function returned a CURLE_COULDNT_CONNECT error code from commit ed1662c374361a and 02fbc26d59c591. This could cause tests 19, 704 and 1233 to fail on FreeBSD, AIX and Solaris.
