Suppress null pointer deref warnings

This is a known issue with bindgen under heavy discussion, but
doesn't look like it will be resolved soon. This attribute
suppresses genuine warnings about undefined behavior in a pattern
generated by bindgen many, many times. It should be removed when
the bindgen issue is resolved.

Until then, it obscures other helpful warnings and errors.
