hwmon: (pmbus/ina233) Add error check for pmbus_read_word_data() return value

ina233_read_word_data() uses the return value of pmbus_read_word_data()
directly in a DIV_ROUND_CLOSEST() computation without first checking for
errors. If the underlying I2C transaction fails, a negative error code is
used in the arithmetic, producing a garbage sensor value instead of
propagating the error.

Add the missing error check before using the return value.
