[SCSI] mpt3sas: cut and paste bug storing trigger mpi
ioc->diag_trigger_mpi is an SL_WH_MPI_TRIGGERS_T struct. There is a cut and paste error here and SL_WH_EVENT_TRIGGERS_T is used instead of SL_WH_MPI_TRIGGERS_T. Since the SL_WH_EVENT_TRIGGERS_T is smaller than SL_WH_MPI_TRIGGERS_T, it means we only clear part of the buffer. I've changed it to use sizeof(ioc->diag_trigger_mpi) which is a bit simpler.
