crda: rename world and prev_world on intersect.c

The assumption was that intersect.c was creating a world
regulatory domain for by doing an intersection of all
regulatory domains. This is technically still true however
it does not add passive scan flag'd frequency ranges and
as such to be precise lets just rename the "world" and
"prev_world" variables as intersection variables.

This change introduces no functional changes.
