7.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: George Wilson <[email protected]>

commit 649c10bff5cb7a514bf299094833ec8c9190aac3 upstream.

The checks on num_vfs in pseries_pci_sriov_enable() are ANDed where OR
was apparently intended.  Change it to OR.

Fixes: 9a7f6b438664 ("powerpc/pseries/pci: Associate PEs to VFs in configure SR-IOV")
