usb; xhci: Fix TRB offset calculations.
Greg KH introduced a bug into xhci_trb_virt_to_dma() when he changed the type of offset to dma_addr_t from unsigned int and dropped the casts to unsigned int around the virtual address pointer subtraction. trb and seg->trbs are both valid pointers to virtual addresses, so the compiler will mod the subtraction by the size of union trb (16 bytes). segment_offset is an unsigned long, which is guaranteed to be at least as big as a void *. Drop the void * casts in the first if statement because trb and seg->trbs are both pointers of the same type (pointers to union trb).
