gpio: acpi: Synchronize acpi_find_gpio() and acpi_gpio_count()

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 resources 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.
