[PATCH] http-push.c: make CURLOPT_IOCTLDATA a usable pointer

[Abbaad Haider <abbaad@gmail.com>]

Fixes a small bug affecting push to remotes which use some sort of
multi-pass authentication. In particular the bug affected SabreDAV as
configured by Box.com [1].

It must be a weird server configuration for the bug to have survived
this long. Someone should write a test for it.
