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.
