x86_64: fix arch_vma_name
The function arch_vma_name() is declared weak and thus it was
not noticed that x86_64 had two almost identical implementations.
It was introduced in syscall32.c by: c633090e3105e779c97d4978e5e3d7d66b291cfb
It was introduced in mm/init.c by: 2aae950b21e4bc789d1fc6668faf67e8748300b7
