[SCSI] aacraid: fix big endian issues

Big endian systems issues discovered in the aacraid driver. Somewhat
reverses a patch from November 7th of last year that removed swap
operations because they formerly were being assigned to an u8 array
when they should have been assigned to an le32 array.

This patch is largely inert for any little endian processor
architecture. It resolves a bug in delivering the BlinkLED AIF event
to registered applications when the adapter or associated hardware was
reset due to ill health. A rare corner case occurrence, also largely
unnoticed by any as it was a new (untested!) feature.
