lib/scatterlist: Fix offset type in sg_alloc_table_from_pages
Scatterlist entries have an unsigned int for the offset so
correct the sg_alloc_table_from_pages function accordingly.
Since these are offsets withing a page, unsigned int is
wide enough.
Also converts callers which were using unsigned long locally
with the lower_32_bits annotation to make it explicitly
clear what is happening.
v2: Use offset_in_page. (Chris Wilson)
