Subject: [PATCH 2/4][next] scsi: megaraid_sas: Replace one-element array with
 flexible-array member in MR_FW_RAID_MAP_DYNAMIC

Replace one-element array with a flexible-array member in struct

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
