ips 1/4: lindent ips.c

From: 	David Jeffery <david_jeffery@adaptec.com>
(with fix ups for rejections on CONFIG_HIGHIO)

This patch has no code changes.  It is only the result of running
scripts/Lindent on drivers/scsi/ips.c in test3.  Rather than use this
patch, it may be advisable to just run 

sh scripts/Lindent drivers/scsi/ips.c 

The nasty 3-4 space indenting in ips.c has always made it a pain to
read.  The remaining patches in this patch set all assume ips.c has been
lindented.
