virtio: uapi: Drop __packed attribute in linux/virtio_pci.h
[ Upstream commit ec6ecb844d14d38b7dae8beb74e3d65db9c7b3e6 ]
Commit 92792ac752aa ("virtio-pci: Introduce admin command sending function")
added "__packed" structures to UAPI header linux/virtio_pci.h. This triggers
build failures in the consumer userspace applications without proper "definition"
of __packed (e.g., kvmtool build fails).
Moreover, the structures are already packed well, and doesn't need explicit
packing, similar to the rest of the structures in all virtio_* headers. Remove
the __packed attribute.
Fixes: 92792ac752aa ("virtio-pci: Introduce admin command sending function")
