Kernel: Add method to clean up remapping region loops

Browse Source 
In the VMObject code there are multiple examples of loops over
the VMObject's regions (using for_each_region()) that call remap()
on each region.

To clean up usage of this pattern, this patch adds a method in
VMObject that does this remapping loop. VMObject code that needs
to remap its regions call the new method.
