kmsan: disable KMSAN when DEFERRED_STRUCT_PAGE_INIT is enabled

KMSAN relies on memblock returning all available pages to it (see
kmsan_memblock_free_pages()).  It partitions these pages into 3
categories: pages available to the buddy allocator, shadow pages and
origin pages.  This partitioning is static.

If new pages appear after kmsan_init_runtime(), it is considered an error.
DEFERRED_STRUCT_PAGE_INIT causes this, so mark it as incompatible with
KMSAN.
