Commit 975bb8b4dc93 ("PCI/IOV: Use VF0 cached config space size for
other VFs") calculates and caches the cfg_size for VF0 device before
initializing the pcie_cap of the device which results in using incorrect
cfg_size for all VF devices > 0. So set pcie_cap of the device before
calculating the cfg_size of VF0 device.

other VFs")
