slam_tomb: simplify and rename to _kill_processes
In general umount_tomb and slam_tomb shared a lot of similar code. Main difference being, that the latter additionally searched for processes and would still call umount_tomb if the processes could be killed. umount_tomb would then again search with the provided name for the relevant tomb in list_tomb_mounts, which should be obsolete at this point. Therefore the decision to reduce slam_tomb in functionality. It would only work on a supplied tombname and tombmount, look if there are processes and is called from within umount_tomb. (Theoretical tombname could be removed) Calling tomb with slam or close sets a flag, which will decide if that part in umount_tomb will be executed.
