Here's a fix. singleipconnect() didn't copy back sockfd to *sockp if
it reached the end of the function (the no-error case).

Had some trouble coming up with a good commit comment! :)

Subject: [PATCH] singleipconnect: Update *sockp for all CURLE_OK

The 56b7c87c7 change left a case where a good sockfd
was not copied to *sockp before returning with CURLE_OK
