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

[ Upstream commit 0fe20fafd1791f993806d417048213ec57b81045 ]
Currently rcode is being initialized to NX_RCODE_SUCCESS and later it
is checked to see if it is not NX_RCODE_SUCCESS which is never true. It
appears that there is an unintentional missing assignment of rcode from
the return of the call to netxen_issue_cmd() that was dropped in
an earlier fix, so add it in.
