[PATCH 5_9] Whitespace fixup on common_cmd_ace.c (using Lindent)

This patch is in preparation of additional changes to the sysace driver.
May as well take this opportunity to fixup the inconsistent whitespace since
this file is about to undergo major changes anyway.

There are zero functional changes in this patch.  It only cleans up the
the whitespace.
