ibmvnic: Check for NULL skb's in NAPI poll routine [ Upstream commit abe27a885d9e6575e663a16176dabc58ce9d7188 ] After introduction of commit d0869c0071e4, there were some instances of RX queue entries from a previous session (before the device was closed and reopened) returned to the NAPI polling routine. Since the corresponding socket buffers were freed, this resulted in a panic on reopen. Include a check for a NULL skb here to avoid this.
