main/curl: fix segfault when running cargo

Patch is taken from upstream at https://github.com/curl/curls
The http2 code for connection checking needs a transfer to use. Make
sure a working one is set before handler->connection_check() is called.

(cherry picked from commit 4a7cbd15d80c1cda6e5221612f846b6b4c91104e)
