softmmu/physmem: Silence GCC 10 maybe-uninitialized error
When building with GCC 10.2 configured with --extra-cflags=-Os, we get:
softmmu/physmem.c: In function 'address_space_translate_for_iotlb':
softmmu/physmem.c:643:26: error: 'notifier' may be used uninitialized in this function [-Werror=maybe-uninitialized]
643 | notifier->active = true;
| ^
softmmu/physmem.c:608:23: note: 'notifier' was declared here
608 | TCGIOMMUNotifier *notifier;
| ^~~~~~~~
Initialize 'notifier' to silence the warning.
