Emil Tantilov 600a507ddc ixgbe: check for vfs outside of sriov_num_vfs before dereference
The check for vfinfo is not sufficient because it does not protect
against specifying vf that is outside of sriov_num_vfs range.
All of the ndo functions have a check for it except for
ixgbevf_ndo_set_spoofcheck().

The following patch is all we need to protect against this panic:

ip link set p96p1 vf 0 spoofchk off
BUG: unable to handle kernel NULL pointer dereference at 0000000000000052
IP: [<ffffffffa044a1c1>]
ixgbe_ndo_set_vf_spoofchk+0x51/0x150 [ixgbe]
