net: mctp: purge receive queues on sk destruction
commit 60bd1d9008a50cc78c4033a16a6f5d78210d481c upstream.
We may have pending skbs in the receive queue when the sk is being
destroyed; add a destructor to purge the queue.
MCTP doesn't use the error queue, so only the receive_queue is purged.
Fixes: 833ef3b91de6 ("mctp: Populate socket implementation")
