[PATCH 5.0 18/36] r8169: fix MAC address being lost in PCI D3

[ Upstream commit 59715171fbd0172a579576f46821031800a63bc5 ]

(At least) RTL8168e forgets its MAC address in PCI D3. To fix this set
the MAC address when resuming. For resuming from runtime-suspend we
had this in place already, for resuming from S3/S5 it was missing.

The commit referenced as being fixed isn't wrong, it's just the first
one where the patch applies cleanly.
