Subject: [PATCH 2/3] x86/fpu: Remove second definition of fpu in __fpu__restore_sig()

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'.

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