[PATCH lora-next 02/11] net: lora: sx130x: Fix error codes

["Andreas Färber" <afaerber@suse.de>]

Use of -ENXIO results in a misleading error message from ip command:

  RTNETLINK answers: No such device or address

Switch to -EIO for more accurate description:

  RTNETLINK answers: Input/output error
