ath10k-firmware: update Candela Tech firmware images

Release notes since last time:

2019-02-08:
  Fix rate-ctrl assert related to bad logic that tried to guess
  that lower bandwidth probes were automatically successful if
  higher was. The NSS mismatch that can happen here caused the
  assert. Just comment out the offending code
  (per comment from original QCA code). This is bug 69.

2019-02-10:
  Fix bssid mis-alignment that broke 4-addr vlan mode (bug 67).
  Original buggy commit was
  commit 2bf89e70ecd1 ("dev-ds: Better packing of wal_vdev struct.")
