ath10k: fix patching mistake for AP/IBSS CSA
Mistakenly v1 of `ath10k: fix AP/IBSS CSA with
template based fw`
(81a9a17db5d766d2872c4ab8a77b8666d22031ec) was
applied.
This patch applies the missing bits from v2:
* remove unnecessary locking
* add some (sanity) checks
There are no practical functionality differences
between v1 and v2.
