Since multiple radios are abstracted under a single wiphy,
apply the rts threshold value to all the vdevs of the radios
combined under single wiphy.

This also implies that vif specific rts threshold support
needs to be added in future from cfg80211/mac80211.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
