x86/PCI: only check for spinlock being held in SMP kernels
spin_is_locked() is always false on UP kernels: spin_lock_irqsave() does no locking, so we can't tell whether the lock is held or not. Therefore, this warning is only valid for SMP kernels. CC: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
