Module Name:    src
Committed By:   riastradh

Modified Files:
        src/sys/net: if_wg.c

Log Message:
wg: mbuf m_freem audit.

1. wg_handle_msg_data frees m but the other wg_handle_msg_* just take
   a pointer to the mbuf content and not m itself, so free m in those
   cases.

2. Can't trivially prove that the pcq is empty by the time
   wg_destroy_peer runs pcq_destroy, so let's explicitly purge it
   just in case.

3. If wg_send_udp isn't doing udp_send or udp6_output, it still has
   to free m in the !INET6 error branch for IPv6 packets.

4. After rumpuser_wg_send_peer or rumpuser_wg_send_user, we still
   need to free the mbuf.
