Can't parse chan info event return from firmware 10.2.4-1.0-00043

Can't parse chan info event return from firmware 10.2.4-1.0-00043

[Steve Brown]

I get "ath10k_pci 0000:03:00.0: failed to parse chan info event: -71"
when scanning.

After some instrumentation, the return is 7 words and the event
structure size is 13 words. This causes the error.

As only the first 6 words are recovered, it's not clear if the problem
is the size of the event structure or the test.

The kernel was built from kvalo/ath.git
7ce94a62264be94dc1c41ff5d0c8a19c7f0d3143.

Samples below.
