[PATCH 2/6][SRU][K] scsi: megaraid_sas: Replace one-element array with flexible-array member in MR_FW_RAID_MAP_DYNAMIC

[AceLan Kao]

From: "Gustavo A. R. Silva" <gustavoars at kernel.org>

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_FW_RAID_MAP_DYNAMIC.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy().
