The original code seems to assume that it's caused by an int3 which another subsystem inserted on out-of-line singlestep buffer if the hitting probe is same as current probe. However, in that case, int3-hitting-address is on the out-of-line buffer and should be different from first (current) int3 address. Thus, I decided to remove the code. I also removes arch_disarm_kprobe() because it will involve other stuffs in text_poke().
