[PATCH 2/3] powernv/pci: Use common code in pnv_ioda_pick_m64_pe()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 17 Oct 2017 17:07:54 +0200

Add a jump target so that a bit of code can be better reused
at the end of this function.
