Subject: [patch] [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.

Only needed in linux-next.

This is a static analysis patch.  Even though I'm pretty sure it's correct, I'm 
not able to test it.
