msm-4.14: Make macros no-op using ((void)0)

Browse Source 
Do not solely rely on compiler optimizations to get the workaround
of having macros do nothing using an empty do-while loop. It's
inefficient.

Use ((void)0) to which the standard assert macro expands when NDEBUG
is defined.

No functional change intended.

[mcdofrenchfreis]:
Implement this patch to tree using the command:
git grep -l "do {} while (0)" | xargs sed -i "s/do {} while (0)/((void)0)/g"
