multi: have curl_multi_remove_handle close CONNECT_ONLY transfer
αΊ‚hen it has been used in the multi interface, it is otherwise left in
the connection cache, can't be reused and nothing will close them since
the easy handle loses the association with the multi handle and thus the
connection cache - until the multi handle is closed or it gets pruned
because the cache is full.

Fixes #9335
Closes #9342
