[PATCH bpf-next v3 1/3] bpf: Simplify assignment to struct bpf_insn pointer in do_misc_fixups()

[Yonghong Song <yonghong.song@xxxxxxxxx>]

In verifier.c, the following code patterns (in two places)
  struct bpf_insn *patch = &insn_buf[0];
can be simplified to
  struct bpf_insn *patch = insn_buf;
which is easier to understand.
