Subject: [PATCH] max17042_battery: Fix error handling

In max17042_get_property(...), the values returned by
max17042_read_reg are directly assigned to the variables,
even if the read results in an error.

This patch checks for the return code from max17042_read_reg and
exits the function if there is any error.
