Subject: [ 39/64] remoteproc: fix error path of handle_vdev

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sjur Brændeland <sjur.brandeland@...ricsson.com>

commit cde42e076c1cdd69a1f955d66ff6596bad3d2105 upstream.

Remove the vdev entry from the list before freeing it,
otherwise rproc->vdevs will explode.
