iio: inkern: Remove the 'unused' variable usage in iio_channel_read_max()

Browse source

The code uses a local variable to initialize a null pointer in order to
avoid accessing this null pointer later on.

Simply removed the 'unused' variable and check for the null pointer just
before accessing it.
