patches bug in recv_mmsg when npkts != nrecv (backport #22276) (#22280)
* removes total-size from return value of recv_mmsg
(cherry picked from commit 4b24499916)
* patches bug in recv_mmsg when npkts != nrecv
If recv_mmsg receives 2 packets where the first one is filtered out,
then it returns npkts == 1:
https://github.com/solana-labs/solana/blob/01a096adc/streamer/src/recvmmsg.rs#L104-L115
But then streamer::packet::recv_from will erroneously keep the 1st
packet and drop the 2nd one:
https://github.com/solana-labs/solana/blob/01a096adc/streamer/src/packet.rs#L34-L49
To avoid this bug, this commit updates recv_mmsg to always return total
number of received packets. If socket address cannot be correctly
obtained, it is left as the default value which is UNSPECIFIED:

(cherry picked from commit 379feecae5)
