Luke eb38fe4a82 Kernel/VM: Make local_offset in PhysicalRegion::free_page_at unsigned 
Anything above or equal to the 2 GB mark has the left most bit set
(0x8000...), which was falsely interpreted as negative due to
local_offset being signed.

This makes it unsigned by using FlatPtr. To check for underflow as
was intended, lets use Checked instead.

Fixes #4585
