usbip: vhci_hcd indicate failed message
If the return value of vhci_init_attr_group and sysfs_create_group is non-zero, which mean they failed to init attr_group and create sysfs group, so it would better add 'failed' message to indicate that. This patch also change pr_err to dev_err to trace which device is failed.
