The root cause is easy. Basically the brcmfmac driver is not on par with the firmware. brcmfmac uses escan api version 1 and firmware expects version 2. Fixing it is going to be more difficult. Things start to diverge on firmware API level. I already had a patch on the shelf supporting version 2, but it does not match the API your firmware expects.
I was working on supporting multiple vendors, but I need some rework. The scanning issue confirms the need for per-vendor support. Hopefully I can spend some time on it.
