scsi: megaraid_sas: Replace one-element array with flexible-array member in MR_DRV_RAID_MAP
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct MR_DRV_RAID_MAP and refactor the code accordingly.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy().
