bpf: Drop redundant pkt_access from bpf_call_arg_meta

meta->pkt_access is only ever a copy of fn->pkt_access, assigned once in
check_helper_call() and read back in may_access_direct_pkt_data(). Have
may_access_direct_pkt_data() take the bpf_func_proto and read
fn->pkt_access directly, and drop the meta field along with its
assignment.

The only non-NULL caller, check_func_arg(), already has fn in scope; the
remaining callers pass NULL and are unaffected.

No functional change intended.
