Borislav Petkov 93f13a9f96 x86/entry/vsyscall: Fix undefined symbol warning 
Commit:

  3dc33bd30f ("x86/entry/vsyscall: Add CONFIG to control default")

did the ifdef/elif thing but GCC doesn't like that:

  arch/x86/entry/vsyscall/vsyscall_64.c:44:7: warning: "CONFIG_LEGACY_VSYSCALL_NONE" is not defined [-Wundef]
   #elif CONFIG_LEGACY_VSYSCALL_NONE
         ^

Use defined() instead.
