curl: remove 'config' field from OutStruct 
As it was just unnecessary duplicated information already stored in the
'per_transfer' struct and that's around mostly anyway.

The duplicated pointer caused problems when the code flow was aborted
before the dupe was filled in and could cause a NULL pointer access.

Reported-by: Brian Carpenter
Fixes #4807
Closes #4810
