staging: pi433: add index value to write dev_dbg statement

Add index value to the string that will be printed by dev_dbg for better
easier visualisation when debugging. For instance, if I have a big
message payload that will inevitably get split into chunks, it would be
a hassle trying to debug if the offset of the original payload that got
sent at that time.

This patch adds index value to write dev_dbg statement.
