Vlad Buslov fd741f0d9f net/sched: flower: fix error handler on replace ... When replacing a filter (i.e. 'fold' pointer is not NULL) the insertion of new filter to idr is postponed until later in code since handle is already provided by the user. However, the error handling code in fl_change() always assumes that the new filter had been inserted into idr. If error handler is reached when replacing existing filter it may remove it from idr therefore making it unreachable for delete or dump afterwards. Fix the issue by verifying that 'fold' argument wasn't provided by caller before calling idr_remove().
