    Move list types from <linux/list.h> to <linux/types.h>.

broke the build of 'perf'.

If you move "struct list_head" into types.h, this means perf stops
building because it depends upon being able to include linux/list.h
from a userland application and at the same time be able to get the
basic data types without defining __KERNEL__ or similar.

Now that no longer occurs because the bulk of types.h is __KERNEL__
protected and thus the build breaks since "struct list_head" is
never defined.
