locking, kprobes: Annotate the hash locks and kretprobe.lock as raw
The kprobe locks can be taken in atomic context and therefore
cannot be preempted on -rt - annotate it.
In mainline this change documents the low level nature of
the lock - otherwise there's no functional difference. Lockdep
and Sparse checking will work as usual.
