Mathias Nyman d39b5bad86 xhci: Fix crash if scatter gather is used with Immediate Data Transfer (IDT). ... A second regression was found in the immediate data transfer (IDT) support which was added to 5.2 kernel IDT is used to transfer small amounts of data (up to 8 bytes) in the field normally used for data dma address, thus avoiding dma mapping. If the data was not already dma mapped, then IDT support assumed data was in urb->transfer_buffer, and did not take into accound that even small amounts of data (8 bytes) can be in a scatterlist instead. This caused a NULL pointer dereference when sg_dma_len() was used with non-dma mapped data. Solve this by not using IDT if scatter gather buffer list is used.
