staging:iio:ad2s1210: Remove old_data from ad2s1210_state
The variable old_data is a bool type, which only receives the value 'true' in the function ad2s1210_config_write and ad2s1210_config_read. There is no other use for this variable. This patch removes old_data from the ad2s1210_state and from all the function that use it.
