Natalia Petrova 51592cf716 crypto: nitrox - avoid double free on error path in nitrox_sriov_init()
[ Upstream commit 094528b6a5 ]

If alloc_workqueue() fails in nitrox_mbox_init() it deallocates
ndev->iov.vfdev and returns error code, but then nitrox_sriov_init()
calls nitrox_sriov_cleanup() where ndev->iov.vfdev is deallocated
again.

Fix this by nulling ndev->iov.vfdev after the first deallocation.
