When to execute binder_stat_br the e->cmd has been modifying as BR_OK instead of the original return error cmd, in fact we want to know the original return error, such as BR_DEAD_REPLY or BR_FAILED_REPLY, etc. instead of always BR_OK, in order to avoid the value of the e->cmd is always BR_OK, so we need assign the value of the e->cmd to cmd before e->cmd = BR_OK.
