[PATCH] Add parenthesis to IRQ vector macros

[PATCH] Add parenthesis to IRQ vector macros

[Steven Rostedt]

It is not good taste to have macros with additions that do not have
parenthesis's around them.  This patch parethesizes the IRQ vector
macros for x86_64 arch.

Note, this caused me a bit of heart-ache debugging lguest64.
