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.

3 Older Version : 00.00.02.01
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>
