bpf: net: Change do_tcp_setsockopt() to use the sockopt's lock_sock() and capable()

Browse source

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_tcp_setsockopt() to use the sockopt_{lock,release}_sock()
and sockopt_[ns_]capable().
