PCI: endpoint: pci-epf-vntb: Use array_index_nospec() on mws_size[] access

Browse source

Follow common kernel idioms for indices derived from configfs attributes
and suppress Smatch warnings:

  epf_ntb_mw1_show() warn: potential spectre issue 'ntb->mws_size' [r]
  epf_ntb_mw1_store() warn: potential spectre issue 'ntb->mws_size' [w]

Also fix the error message for out-of-range MW indices and %lld format
for unsigned values.
