lib/scatterlist: Do not limit max_segment to PAGE_ALIGNED values
The main intention of the max_segment argument to
__sg_alloc_table_from_pages() is to match the DMA layer segment size set
by dma_set_max_seg_size().
Restricting the input to be page aligned makes it impossible to just
connect the DMA layer to this API.
The only reason for a page alignment here is because the algorithm will
overshoot the max_segment if it is not a multiple of PAGE_SIZE. Simply fix
the alignment before starting and don't expose this implementation detail
to the callers.
A future patch will completely remove SCATTERLIST_MAX_SEGMENT.
