pcie_sriov: Reset SR-IOV extended capability
pcie_sriov_pf_disable_vfs() is called when resetting the PF, but it only
disables VFs and does not reset SR-IOV extended capability, leaking the
state and making the VF Enable register inconsistent with the actual
state.
Replace pcie_sriov_pf_disable_vfs() with pcie_sriov_pf_reset(), which
does not only disable VFs but also resets the capability.
