core/mmu.cc: silence warning

gcc 11 warns about the MMU code writing 4096 byte to an area with 0 bytes. I am guessing this is a false alarm, but the code is too convoluted for me to prove it :-( So for now, let's just slience this build error. Signed-off-by: Nadav Har'El <[email protected]> Message-Id: <[email protected]>
