lockable: add QEMU_MAKE_LOCKABLE_NONNULL

This will be needed for lock guards, because if the lock is NULL the
dummy for loop of the lock guard never runs.  This can cause confusion
and dummy warnings in the compiler, but even if it did not, aborting
with a NULL pointer dereference is a less surprising behavior.
