ppdev: Add an error check in register_device
In register_device, the return value of ida_simple_get is unchecked,
in witch ida_simple_get will use an invalid index value.
To address this issue, index should be checked after ida_simple_get. When
the index value is abnormal, a warning message should be printed, the port
should be dropped, and the value should be recorded.
