pci, devices, virtio-devices, vmm: Refactor allocate_bars

Browse Source 
Refactor PciDevice::allocate_bars trait and all implementations
to take &mut SystemAllocator instead of &Arc<Mutex<SystemAllocator>>,
removing double indirection.

The caller in device_manager.rs now acquires the lock before
calling allocate_bars.
