scsi: mpt3sas: Make MPI26_CONFIG_PAGE_PIOUNIT_1::PhyData[] a flexible array

Browse source

This terminal 1-length variable array can be directly converted into a C99
flexible array member.

As all users of MPI26_CONFIG_PAGE_PIOUNIT_1 (Mpi26PCIeIOUnitPage1_t) do not
use PhyData[], no further source changes are required to accommodate its
reduced sizeof():

 - mpt3sas_config.c:mpt3sas_config_get_pcie_iounit_pg1() fetches a
   Mpi26PCIeIOUnitPage1_t into a caller-provided buffer, and may fetch
   and write PhyData[] into that buffer depending on its sz argument.
   It has one caller:

   - mpt3sas_base.c:_base_assign_fw_reported_qd() passes
     sizeof(Mpi26PCIeIOUnitPage1_t) as sz, but does not use PhyData[].
