x86/entry/vsyscall: Fix undefined symbol warning
Commit:
3dc33bd30f3e1 ("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.
