scsi: mpt3sas: Remove the iounit_pg8 member of the per-adapter struct
The per-adapter struct (struct MPT3SAS_ADAPTER) contains a
MPI2_CONFIG_PAGE_IO_UNIT_8 (Mpi2IOUnitPage8_t) iounit_pg8 member that is
populated by mpt3sas_base.c:_base_static_config_pages().
As the name of that function indicates, the iounit_pg8 member represents a
static configuration page data structure that rarely changes, and is among
several such static config pages that are currently being fetched once per
adapter per init (or reset) and copied to the per-adapter struct for later
use.
However, unlike the other static config pages, the iounit_pg8 member is
never actually used outside of _base_static_config_pages(). Also,
Mpi2IOUnitPage8_t has a flexible array member, making its presence in the
_middle_ of the per-adapter struct rather strange.
Remove this member from the per-adapter struct and fix up the portion of
_base_static_config_pages() that uses it.
