fix: 'Oh snap' error when creating VPC from Linode Create (linode#10783)

* add undefined checker

* this should do it

* fixed still existing regression + maintained Edit Config behavior, still some weird flicker

* add back in clearIcon prop

* Update packages/manager/src/features/Linodes/LinodesCreate/VPCPanel.tsx
