SG: Change sg_set_page() to take length and offset argument

Browse source 
Most drivers need to set length and offset as well, so may as well fold
those three lines into one.

Add sg_assign_page() for those two locations that only needed to set
the page, where the offset/length is set outside of the function context.

* can be rewritten as

* sg_set_page(virt_to_page(some_ptr));
* sg->offset = (unsigned long) some_ptr & ~PAGE_MASK;
* sg_set_buf(sg, some_ptr, length);
*
* and that's it. There's no excuse for not highmem enabling YOUR driver. /jens
