Revert "kprobes: Warn if optprobe handler tries to change execution path"
This reverts commit:
e863d539614641 ("kprobes: Warn if optprobe handler tries to change execution path")
On PowerPC, we place a probe at kretprobe_trampoline to catch function
returns and with CONFIG_OPTPROBES=y, this probe gets optimized. This
works for us due to the way we handle the optprobe as described in
commit:
762df10bad6954 ("powerpc/kprobes: Optimize kprobe in kretprobe_trampoline()")
With the above commit, we end up with a warning. As such, revert this change.
