[PATCH] x86_64: Remove duplicated FAKE_STACK_FRAME macro.

Remove duplicated FAKE_STACK_FRAME macro.

FAKE_STACK_FRAME macro is defined twice.  The one that gets used is in
arch/x86_64/kernel/entry.S, and is slightly different codewise, although
should have the same end result (uses pushq rather than addq %rsp + movq and
has the extra dwarf annotations).
