kasan/test: only do kmalloc_double_kzfree for generic mode
kmalloc_double_kzfree() would corrupt kernel memory when the just freed
memory were allocated by another thread before the second call to
kfree_sensitive() and the new allocation tag happened to match the old
one.
This could not happen in GENERIC mode as it uses quarantine.
