Fix the check for devm_reset_control_array_get_exclusive() return value. The devm_reset_control_array_get_exclusive() function may return NULL if it's an optional request. If optional is intended then NULL should not be treated as an error case, but as a special kind of success case. So here the IS_ERR() is used to check better.
