parselogs: Whitelist qemux86 error message with qemu 2.7.0

qemu 2.7.0 introduces kernel errors:

[    2.310768] pci 0000:00:00.0: [11ab:4620] type 00 class 0x060000

[    2.315363] pci 0000:00:0a.1: [8086:7111] type 00 class 0x010180

Whitelist this for now since this is preferable to the random failures
we're seeing from qemuppc with 2.6.0.
