UBI: clean-up terminology for self-checks in io.c
We have the "sefl-check" feature in UBI, but for historical reasons many corresponding functions and commentaries in the code use term "paranoid check" instead. Let's clean this up and use "self-check" everywhere. This patch renames functions, amends comments and messages. It touches only the io.c file.
