Removed dead code from a macro in zmalloc.cpp

Browse Source 
I think the compiler would have removed this no-op anyways but it
definitely wasted me some 30 minutes on this :(

I was hoping I could remove the branch through some bit-hacking but
apparently its dead code :). Oh well, its 30 minutes of refreshing
bit hacking.
