openingd: Remove dust check for reserve imposed on us

Browse Source 
This check, while in line with the specification, would cause issues
in mixed setups when the funder or fundee allows dust reserves, but
the counterparty does not. It is not an issue for the non-dust reserve
node since in this case it's the peer giving us more flexibility not
the other way around.
