mpi3mr: Check for copyin errors in mpi3mr_map_data_buffer_dma()

A failed copyin will cause the driver to use the contents of
uninitialized buffers instead, which is unlikely to be the behaviour
that we want. Check for errors.

This is in preparation for annotating copyin() and related functions
with __result_use_check.

mpi3mr: Assume dma_hiaddr is BUS_SPACE_MAXADDR

No sense having a variable for this. So use BUS_SPACE_MAXADDR and remove
dma_hiaddr from softc.

mpi3mr: Make these bus_dmamap_load calls synchronous

These calls "should" all be synchrounous. There's no bouncing that's
needed for them (at least in the typical case that we have a sane card
that has more bits of dma addresses decoded than we have memory), so
there's no errors possible. Ensure these calls are really synchronous
with BUS_DMA_NOWAIT flags (which should never fail now that the
bus_dmamem_alloc() has succeeded).

mpi3mr: fix GCC kernel build

Previously every file that included mpi3mr_app.h but did not use
mpi3mr_mgmt_info reported error: 'mpi3mr_mgmt_info' defined but not
used.

mpi3mr: 3rd Generation Tri-Mode NVMe/SAS/SATA MegaRaid / eHBA

This is Broadcom's mpi3mr driver for FreeBSD version 8.6.0.2.0.
The mpi3mr driver supports Broadcom SAS4116-based cards in the 9600
series: 9670W-16i, 9670-24i, 9660-16i, 9620-16i, 9600-24i, 9600-16i,
9600W-16e, 9600-16e, 9600-8i8e.

Initially only available as a module and on amd64/arm64, since that's
how it has been tested to date. Future commits will add it to the kernel
build and may expand the architectures it is supported on.
