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', as the two definitions are the same.
