rtos/FreeRTOS: fix next pointer member offset in FreeRTOS lists

Browse Source 
Currently, we are using offset of xListEnd.pxPrevious in List_t for
list_next_offset and offset of pxPrevious in ListItem_t for
list_elem_next_offset. This is confusing. Fix this.
As the related lists are doubly linked lists, only iteration order is
changed without breaking functionality.
Also document those offsets.
