If we pass connection ID to the both functions and at the same time acpi_can_fallback_to_crs() returns false we will get different results, i.e. the number of GPIO resourses returned by acpi_gpio_count() might be not correct.
Fix this by calling acpi_can_fallback_to_crs() in acpi_gpio_count() before trying to fallback.
