Dylan Reid 4ba1d2274e qcow: disallow crazy l1 table sizes ...

Before this change, a corrupt or malicious qcow file could cause crosvm
to allocate absurd amounts of memory. The fuzzer found this case,
limit the L1 table size so it can't cause issues.

BUG=chromium:974123
TEST=run fuzzer locally, add unit test
