virtio_pci: modify ENOENT to EINVAL
[ Upstream commit b66ead2d0ecac00c3a06a6218af5411cb5fcb5d5 ]
Virtio_crypto use max_data_queues+1 to setup vqs,
we use vp_modern_get_num_queues to protect the vq range in setup_vq.
We could enter index >= vp_modern_get_num_queues(mdev) in setup_vq
if common->num_queues is not set well,and it return -ENOENT.
It is better to use -EINVAL instead.
