cpu-exec: Fix direct jump to TB spanning page
It is not safe to make a direct jump to a TB spanning two pages in
system emulation because the mapping for the second page can get changed
but we don't take care of direct jumps in this case.
However in user mode emulation, this is not the case because there's
only static address translation and TBs are always invalidated properly.
Fixes: 5b053a4a2827 ("tcg: Clean up direct block chaining safety checks")
