FastLinQ devices as a complex systems may observe various hardware
level error conditions, both severe and recoverable.

Driver is able to detect and report this, but so far it only did
trace/dmesg based reporting.

Here we implement an extended hw error detection, service task
handler captures a dump for the later analysis.

I also resubmit a patch from Denis Bolotin on tx timeout handler,
addressing David's comment regarding recovery procedure as an extra
reaction on this event.
