PCI: endpoint: pci-epf-vntb: Return -ENOENT if pci_epc_get_next_free_bar() fails

Browse Source 
[ Upstream commit 7ea488cce73263231662e426639dd3e836537068 ]

According the function documentation of epf_ntb_init_epc_bar(), the
function should return an error code on error. However, it returns -1 when
no BAR is available i.e., when pci_epc_get_next_free_bar() fails.

Return -ENOENT instead.
