pci-assign: Remove bogus PCIe lnkcap wmask setting

All the fields of lnkcap are read-only and this is setting it
with mask values from LNKCTL.  Just below it, we indicate
link control is read only, so this appears to be a stray
chunk left in from development.  Trivial comment fix while
we're here.
