[PATCH] kprobes: drop the unnecessary unlikely()

[l3b2w1]

From: "binglei.wang" <l3b2w1@xxxxxxxxx>

!ap is likely when checking re-registering existing kprobe.
	register_kprobe -> warn_kprobe_rereg -> __get_valid_kprobe

!ap is unlikely when checking whether the kprobe is valid
on enable/disable ocassion.
	__disable_kprobe/enable_kprobe -> __get_valid_kprobe

Considering these two cases, choose to drop the unlikely() here.
