target/i386: allow access_ptr to force slow path on failed probe

When we are using TCG plugin memory callbacks probe_access_internal
will return TLB_MMIO to force the slow path for memory access. This
results in probe_access returning NULL but the x86 access_ptr function
happily accepts an empty haddr resulting in segfault hilarity.

Check for an empty haddr to prevent the segfault and enable plugins to
track all the memory operations for the x86 save/restore helpers. As
we also want to run the slow path when instrumenting *-user we should
also not have the short cutting test_ptr macro.

Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2489
Fixes: 6d03226b42 (plugins: force slow path when plugins instrument memory ops)
