[PATCH bpf-next 09/14] bpf: add parenthesis around argument of BPF_LDST_BYTES()

[Jakub Kicinski]

BPF_LDST_BYTES() does not put it's argument in parenthesis
when referencing it.  This makes it impossible to pass pointers
obtained by address-of operator (e.g. BPF_LDST_BYTES(&insn)).
Add the parenthesis.
