[PATCH v2 03/13] iio: chemical: Remove redundant dev_err()/dev_err_probe()

Since commit
55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"),
devm_request_irq() and devm_request_threaded_irq() automatically log
detailed error messages on failure. Remove the now-redundant
driver-specific dev_err() and dev_err_probe() calls.
