Joanne Koong bbd52178e2 bpf: Fix bpf_xdp_pointer return pointer 
For the case where offset + len == size, bpf_xdp_pointer should return a
valid pointer to the addr because that access is permitted. We should
only return NULL in the case where offset + len exceeds size.

Fixes: 3f364222d0 ("net: xdp: introduce bpf_xdp_pointer utility routine")
