src/arch/x86/exit_car: Fix regression on x86_64

The commit d023909b "treewide: Disable R_AMD64_32S relocation support"
clflush the address stored in _cbmem_top_ptr, which is the same address
cbmem_top() returns, instead of clflush _cbmem_top_ptr itself.

Fix that by providing the correct address to clflush.
