We used to map doorbell register after FW enable request is complete.
This causes a race condition when unsolicited event is received, and FW
sends a CQE for it. Since the doorbell is not mapped, driver does not
arm CQ, which means FW will not notify the driver for further CQ
completions.  To resolve this, map the doorbell between offload and
enable, so that driver is ready to receive the unsolicited packets and
arm the CQ as soon as FW enable is performed.

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.
