libstore: remove TransferItem::active

Browse source 
it's always legal to call curl_multi_remove_handle on a valid pair of
multi and easy handles. removing an easy handle that is not currently
attached to a multi handle is a no-op, and removing an easy handle of
a different multi handle is something we can't reasonably trigger. if
we *did* ever manage it would result in an error we'd ignore, and the
handles in question would not be changed at all. this is just simpler
