iio: light: fix improper return value
In function cm3232_reg_init(), it returns 0 even if the last call to i2c_smbus_write_byte_data() returns a negative value (indicates error). As a result, the return value may be inconsistent with the execution status, and the caller of cm3232_reg_init() will not be able to detect the error. This patch fixes the bug.
