fa1433ac1be8481f08c1a0a311a6b87d8a874c6a rpc: Remove special case for unknown service flags (MarcoFalke)
Pull request description:
The special case to return a bit as an integer is clumsy and undocumented. Probably also irrelevant because there shouldn't currently be a non-misbehaving client that connects to Bitcoin Core and advertises an unknown service flag.
Thus, simply remove the code.
