malloc: return NULL if not initialized yet

When malloc() was called before it was properly initialized
(as would happen if when used before relocation to RAM) it returned
random, non-NULL values, which called all kinds of difficult to debug
subsequent errors.

Make sure to return NULL when initialization was not done yet.
