mergify[bot] 1be989c5d2 adds fallback logic if retransmit multicast fails (backport #17714 ) (#18498 )

* adds fallback logic if retransmit multicast fails (#17714)

In retransmit-stage, based on the packet.meta.seed and resulting
children/neighbors, each packet is sent to a different set of peers:
https://github.com/solana-labs/solana/blob/708bbcb00/core/src/retransmit_stage.rs#L421-L457

However, current code errors out as soon as a multicast call fails,
which will skip all the remaining packets:
https://github.com/solana-labs/solana/blob/708bbcb00/core/src/retransmit_stage.rs#L467-L470

This can exacerbate packets loss in turbine.

This commit:
  * keeps iterating over retransmit packets for loop even if some
    intermediate sends fail.
  * adds a fallback to UdpSocket::send_to if multicast fails.
