bpf: net: Change do_ip_setsockopt() to use the sockopt's lock_sock() and capable()
Similar to the earlier patch that avoids sk_setsockopt() from
taking sk lock and doing capable test when called by bpf. This patch
changes do_ip_setsockopt() to use the sockopt_{lock,release}_sock()
and sockopt_[ns_]capable().
