[PATCH ath-next 3/5] wifi: ath11k: leave OBSS PD off when spatial reuse is not configured

[Andrei-Alexandru Bleortu]

mac80211 reports BSS_CHANGED_HE_OBSS_PD when an HE AP starts even if
user space configured no spatial reuse parameters, with he_obss_pd
.enable false. ath11k ignored the flag and, with an empty SR Control,
enabled non-SRG OBSS PD at its default maximum threshold of -62 dBm,
where IEEE Std 802.11-2024, 26.10.2.4 puts the non-SRG OBSS PD maximum
at -82 dBm plus an offset that the AP did not advertise.

Disable OBSS PD unless it is enabled, as ath12k does.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.9.0.1-02146-QCAHKSWPL_SILICONZ-1
