[PATCH] reduce MAX_NR_ZONES: fix MAX_NR_ZONES array initializations

Fix array initialization in lots of arches

The number of zones may now be reduced from 4 to 2 for many arches.  Fix the
array initialization for the zones array for all architectures so that it is
not initializing a fixed number of elements.
