From: Carolyn Wyborny <carolyn.wybo...@intel.com>
This patch fixes an issue in the virt channel code, where a return
from i40e_find_vsi_from_id was not checked for NULL when applicable.
Without this patch, there is a risk for panic and static analysis
tools complain. This patch fixes the problem by adding the check
and adding an additional input check for similar reasons.
