x86, io_apic.c: Work around compiler warning

Browse source

This compiler warning:

  arch/x86/kernel/apic/io_apic.c: In function ‘ioapic_write_entry’:
  arch/x86/kernel/apic/io_apic.c:466: warning: ‘eu’ is used uninitialized in this function
  arch/x86/kernel/apic/io_apic.c:465: note: ‘eu’ was declared here

Is bogus as 'eu' is always initialized. But annotate it away by
initializing the variable, to make it easier for people to notice
real warnings. A compiler that sees through this logic will
optimize away the initialization.
