iio: light: ltrf216a: fix runtime PM reference leak in error path

ltrf216a_get_lux() acquires a runtime PM reference by calling
ltrf216a_set_power_state(data, true). However, if
ltrf216a_read_data() fails, the function returns immediately without
dropping the reference.

This leaves the runtime PM usage count unbalanced, preventing the device
from autosuspending after a failed read.

Fix this by releasing the runtime PM reference before returning from the
error path.
