Kernel/Memory: Fix UNMAP_AFTER_INIT page fault handling

Browse source 
This was discovered by me during a work on USB keyboard patches, so it
triggered this bug.

The printing format for the VirtualAddress part is incorrect, leading to
another crash when handling page fault after accessing UNMAP_AFTER_INIT
code section.
