[x86 setup] Handle case of improperly terminated E820 chain
At least one system (a Geode system with a Digital Logic BIOS) has
been found which suddenly stops reporting the SMAP signature when
reading the E820 memory chain. We can't know what, exactly, broke in
the BIOS, so if we detect this situation, declare the E820 data
unusable and fall back to E801.
Also, revert to original behavior of always probing all memory
methods; that way all the memory information is available to the
kernel.
