x86/stackframe, x86/kprobes: Fix frame pointer annotations

Browse source

The kprobe trampolines have a FRAME_POINTER annotation that makes no
sense. It marks the frame in the middle of pt_regs, at the place of
saving BP.

Change it to mark the pt_regs frame as per the ENCODE_FRAME_POINTER
from the respective entry_*.S.
