PCI: endpoint: Drop superfluous pci_epc_features initialization

struct pci_epc_features has static storage duration, so all struct members
are zero initialized implicitly. Thus, remove explicit zero initialization
for features that are *not* supported so we don't have to touch existing
drivers as new features are added.
