Fix recvmmsg decode: do not show more data than actually returned

This change complements recent fix for recvmsg decoding.

* net.c (printmmsghdr): Add msg_len parameter to pass down to do_msghdr.
When this parameter is zero, pass mmsghdr.msg_len to do_msghdr instead.
(decode_mmsg): Add msg_len parameter, pass it down to printmmsghdr.
(sys_sendmmsg): Call decode_mmsg with msg_len == (unsigned long) -1L.
(sys_recvmmsg): Call decode_mmsg with msg_len == 0.
