[Bug] snarkOS aggressively disconnects peers

[HarukaMa]

🐛 Bug Report

SnarkOS reports protocol violation and disconnects when peers send known solutions.

The inbound function returns error when it receives a known solution:
https://github.com/AleoHQ/snarkOS/blob/8be6ac9a3d2c119d2a2282ba74a0d0886a30a521/node/router/src/inbound.rs#L212-L213

However, it will be regarded as a protocol violation:
https://github.com/AleoHQ/snarkOS/blob/8be6ac9a3d2c119d2a2282ba74a0d0886a30a521/node/src/client/router.rs#L116-L122

Steps to Reproduce

Run node with verbosity 5, observe the logs.
