3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>
commit ff6b8090e26ef7649ef0cc6b42389141ef48b0cf upstream.
we have already allocated memory for nbd_dev, but we were not
releasing that memory and just returning the error value.
