x86/apic: Remove local var in flat_send_IPI_allbutself()
No code changed:
# arch/x86/kernel/apic/apic_flat_64.o:
text data bss dec hex filename
1838 624 0 2462 99e apic_flat_64.o.before
1838 624 0 2462 99e apic_flat_64.o.after
md5:
aa2ae687d94bc4534f86ae6865dabd6a apic_flat_64.o.before.asm
42148da76ba8f9a236c33f8803bd2a6b apic_flat_64.o.after.asm
md5 sum is different due to asm output offsets changing.
