[IA64] unwind: remove preprocesser noise, and correct comment
The expression in the comment was mis-bracketted. There was also no need to introduce a coding-style breaking macro for a single use, so just made it a static const. Signed-off-by: Phil Carmody <ext-phil.2.carmody@nokia.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
