[SCSI] aacraid: remove pigs in space

I was amazed at how much embedded space was present in the aacraid
driver source files. Just selected five files from the set to clean up
for now and the attached patch swelled to 73K in size!

- Removed trailing space or tabs
- Removed spaces embedded within tabs
- Replaced leading 8 spaces with tabs
- Removed spaces before )
- Removed ClusterCommand as it was unused (noticed it as one triggered by above)
- Replaced scsi_status comparison with 0x02, to compare against SAM_STATUS_CHECK_CONDITION.
- Replaced a long series of spaces with tabs
- Replaced some simple if...defined() with ifdef/ifndef
