x86/apic: Get rid of "warning: 'acpi_ioapic_lock' defined but not used"
kbuild test robot reported this against the -RT tree:
|>> arch/x86/kernel/acpi/boot.c:90:21: warning: 'acpi_ioapic_lock' defined but not used [-Wunused-variable]
| static DEFINE_MUTEX(acpi_ioapic_lock);
| ^
| include/linux/mutex_rt.h:27:15: note: in definition of macro 'DEFINE_MUTEX'
| struct mutex mutexname = __MUTEX_INITIALIZER(mutexname)
^~~~~~~~~
which is also true (as in non-used) for !RT but the compiler does not
emit a warning.
