MDEV-9044 : Binlog corruption in Galera

While refreshing the IO_CACHE, do not update its parameters (read_pos, read_end & pos_in_file) if there is nothing left to read.

I'm sorry, but I don't understand the fix. Why should parameters be not updated? If there's nothing left to read, the cache is marked as empty, that seems to be correct.
