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.
