[SCSI] megaraid_sas: cleanup queue command path

This patch (originally submitted by Christoph Hellwig) removes code
duplication in megasas_build_cmd.  It also defines
MEGASAS_IOC_FIRMWARE32 to allow 64 bit compiled applications to work.

+
+i.      Code reorganized to remove code duplication in megasas_build_cmd. 
+
+        "There's a lot of duplicate code megasas_build_cmd.  Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"
+
+                - Christoph Hellwig <hch@lst.de>
+
+ii.     Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
+
+        "MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"

+                - Christoph Hellwig <hch@lst.de>
