x86_64/memory: fix return in scoped_mapping::map
Previously, scoped_mapping::map returned the start address of the frame.
Unfortunately, the initial mapping performed in the bootstrap code maps
physical memory starting at 0x0000'0000'0000'0000, which means no fault
was triggered. The map function now correctly return the start address
of the scoped_mapping's page, which must alway work by definition.
