bpf: Use given function address for trampoline ip arg
Using function address given at the generation time as the trampoline
ip argument. This way we get directly the function address that we
need, so we don't need to:
- read the ip from the stack
- subtract X86_PATCH_SIZE
- subtract ENDBR_INSN_SIZE if CONFIG_X86_KERNEL_IBT is enabled
which is not even implemented yet ;-)
