vfio-pci/nvlink2: Fix ancient gcc warnings
Using the {0} construct as a generic initializer is perfectly fine in C,
however due to a bug in old gcc there is a warning:
+ /kisskb/src/drivers/vfio/pci/vfio_pci_nvlink2.c: warning: (near
initialization for 'cap.header') [-Wmissing-braces]: => 181:9
Since for whatever reason we still want to compile the modern kernel
with such an old gcc without warnings, this changes the capabilities
initialization.
