ath10k-ct-firmware: update qca988X firmware to latest beta version

Release Notes:

* Attempt to fix crash in scanning logic by making probe_timer
  ignore re-arm.

Candela Technologies has already used this beta firmware in their
commercial product "LANforge". On QCA9882, I didn't catch any speed
or stability issues compared to the previous version. Therefore, I
think it is worth updating this beta version.
