[PATCH] vdpa: Fix file descriptor leak on get features error |

File descriptor vdpa_device_fd is not free in the case of returning
error from vhost_vdpa_get_features. Fixing it by making all errors go to
the same error path.
Resolves: Coverity CID 1490785
Fixes: 8170ab3f43 ("vdpa: Extract get features part from
vhost_vdpa_get_max_queue_pairs")
