A dbCa link does a ca_get with type DBR_CTRL_DOUBLE to populate its list of attribute values immediately after connecting. If the target is a DBF_*LINK field it used to return an error, preventing the link from properly connecting. This change makes dbGetField() return a single NAN value instead of rejecting the request.
