Daniel Borkmann 4dc6e55e28 bpf: Move sanitize_val_alu out of op switch ...

commit f528819334 upstream.

Add a small sanitize_needed() helper function and move sanitize_val_alu()
out of the main opcode switch. In upcoming work, we'll move sanitize_ptr_alu()
as well out of its opcode switch so this helps to streamline both.
