Subject: i40e/virtchnl: fix application of sizeof to pointer
Patch-mainline: v4.15-rc2
Git-commit: c30bf8cecebabb119aa1fbb17de84f924a8ab8f7
References: bsc#1101816 FATE#325147 FATE#325149

sizeof when applied to a pointer typed expression gives the size of
the pointer.

The proper fix in this particular case is to code sizeof(*vfres)
instead of sizeof(vfres).

This issue was detected with the help of Coccinelle.
