nvk: Unconditionally zero image format properties

It seems like this shouldn't be neded but some of the tests complain if
we don't because they call vkGetPhysicalDeviceImageFormatProperties()
and vkGetPhysicalDeviceImageFormatProperties2() and compare if they
return identical results even if they return error.  Zero is the
reasonable thing to do if you don't support a format anyway because then
it's a maximum extent, sample count, etc. of zero.
