Subject: [PATCH V6 06/11] megaraid_sas: Dynamic Raid Map Changes for SAS3.5 Generic Megaraid Controllers

SAS3.5 Generic Megaraid Controllers FW will support new dynamic RaidMap to have different
sizes for different number of supported VDs.

This patch is depending on patch 5

80 chars per line limit is taken care around VD_EXT_DEBUG macro.
NULL pointer check for desc_table has been removed.
Few code indentation issues fixed.
