mtest: remove braindamaged NULL pointer deref 

The alternative memory test implementation needs a scratch
memory location to remove the last data from the data bus.
Instead of using a NULL pointer for this, default to the
memory start address.
No sane program should consider a NULL pointer as a safe default.
