[PATCH 2/2] ath10k: fix pmf for wmi-tlv on qca6174

[Michal Kazior]

From: Marek Kwaczynski <marek.kwaczynski at tieto.com>

New wmi-tlv firmware uses HTT 3.0 protocol which
uses TX_FRM command for management frames (instead
of a dedicated command). To support PMF it is
necessary to provide explicit tailroom.
