Kumar Kartikeya Dwivedi 812f7702d8 bpf, x86: Fix objtool warning for timed may_goto ...

Kernel test robot reported "call without frame pointer save/setup"
warning in objtool. This will make stack traces unreliable on
CONFIG_UNWINDER_FRAME_POINTER=y, however it works on
CONFIG_UNWINDER_ORC=y. Fix this by creating a stack frame for the
function.
