ixgbe: fix end of loop test in ixgbe_set_vf_macvlan()
The list iterator in a list_for_each_entry() loop can never be NULL.
If the loop exits without hitting a break then the iterator points
to an offset off the list head and dereferencing it is an out of
bounds access.
Before we transitioned to using list_for_each_entry() loops, then
it was possible for "entry" to be NULL and the comments mention
this. I have updated the comments to match the new code.
Fixes: c1fec890458a ("ethernet/intel: Use list_for_each_entry() helper")
