ALSA: scarlett2: Fix buffer overflow in config retrieval

The scarlett2_usb_get_config() function has a logic error in the endianness conversion code that can cause buffer overflows when count > 1.

The code checks if (size == 2) where size is the total buffer size in bytes, then loops count times treating each element as u16 (2 bytes). This causes the loop to access count * 2 bytes when the buffer only has size bytes allocated.

Fix by checking the element size (config_item->size) instead of the total buffer size. This ensures the endianness conversion matches the actual element type.
