iio: pressure: bmp280: Use IS_ERR() in bmp280_common_probe()
commit 43c0f6456f801181a80b73d95def0e0fd134e1cc upstream.
`devm_gpiod_get_optional()` may return non-NULL error pointer on failure.
Check its return value using `IS_ERR()` and propagate the error if
necessary.
Fixes: df6e71256c84 ("iio: pressure: bmp280: Explicitly mark GPIO optional")
