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.
