[RFT][PATCH 3.0] ssb: fix PCI(e) driver regression causing oops on PCI cards

["Rafał Miłecki" <zajec5@gmail.com>]

We were incorrectly executing PCIe specific workarounds on PCI cards.
This resulted in:
Machine check in kernel mode.
Caused by (from SRR1=149030): Transfer error ack signal
Oops: Machine check, sig: 7 [#1]
