Thread might create a condition for delayed SU cleanup, which creates a reference to the mount point in td_su, but exit without returning through userret(), e.g. when terminating due to single-threading or process exit. In this case, td_su reference is not dropped and mount point cannot be freed. Handle the situation by clearing td_su also in the thread destructor and in exit1(). softdep_ast_cleanup() has to receive the thread as argument, since e.g. thread destructor is executed in different context.
