x86/kprobes: Cleanup kprobes on ftrace code
Cleanup kprobes on ftrace code for x86.
- Set instruction pointer (ip + MCOUNT_INSN_SIZE) after pre_handler only
when p->post_handler exists.
- Use INT3_INSN_SIZE instead of 1.
- Use instruction_pointer/instruction_pointer_set() functions instead of
accessing regs->ip directly.
