Filipe Manana d611add48b btrfs: fix reclaim counter leak of space_info objects ... Whenever we add a ticket to a space_info object we increment the object's reclaim_size counter witht the ticket's bytes, and we decrement it with the corresponding amount only when we are able to grant the requested space to the ticket. When we are not able to grant the space to a ticket, or when the ticket is removed due to a signal (e.g. an application has received sigterm from the terminal) we never decrement the counter with the corresponding bytes from the ticket. This leak can result in the space reclaim code to later do much more work than necessary. So fix it by decrementing the counter when those two cases happen as well.
