devices: vvu: handler: only pass needed data to HandlerType

When using VVU, the DeviceRequestHandler only needs a reference to the
VFIO device, the PCI caps, and the notification events. There is no need
to share a reference to the whole VvuPciDevice, and releasing that
reference will actually allow us to remove it as well as the
VvuPciDevice mutex in a future CL.

BUG=b:194137301
TEST=VVU block device works.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
