ath11k_nss: fix null chanctx warning for NSS dynamic VLAN

Browse Source 
Patch is updated to match closer to QSDK's implementation for
ath11k/12k. The null chanctx warning is likely due to the way NSS is
managing the interface. This patch (for now) is a workaround to prevent
the BUG_ON() from triggering for dynamic VLANs.
