bpf: don't mark FP reg as uninit when verifier hits an internal bug don't mark register R10==FP as uninit, since it's read only register and it's not technically correct to let verifier run further, since it may assume that R10 has valid auxiliary state. While developing subsequent patches this issue was discovered, though the code eventually changed that aux reg state doesn't have pointers any more it is still safer to avoid clearing readonly register.
