net: don't ignore getsockname errors in newFileFD
newFileFD is called when creating a net FD from an existing socket
handle. That socket might not be bound yet, in which case getsockname
returns a useful error that is currently ignored and replaced with a
potentially misleading EPROTONOSUPPORT error later on.
