i40evf: check for msix_entries null dereference
It is possible for msix_entries to be freed by a previous suspend/remove
before a VF is closed. This patch fixes the issue by checking for NULL
before dereferencing msix_entries and returning early in the case where
it is NULL within the i40evf_close code path. Without this patch it is
possible to trigger a kernel panic through NULL dereference.
