x86/fpu: Remove second definition of fpu in __fpu__restore_sig()

[ Upstream commit 6aa676761d4c1acfa31320e55fa1f83f3fcbbc7a ]

Commit:

  c5bedc6847c3b ("x86/fpu: Get rid of PF_USED_MATH usage, convert it to fpu->fpstate_active")

introduced the 'fpu' variable at top of __restore_xstate_sig(),
which now shadows the other definition:

  arch/x86/kernel/fpu/signal.c:318:28: warning: symbol 'fpu' shadows an earlier one
  arch/x86/kernel/fpu/signal.c:271:20: originally declared here

Remove the shadowed definition of 'fpu', as the two definitions are the same.
