ath11k_nss: fix WDS instability by disabling NAWDS mode

Browse Source 
This patch replaces the problematic NAWDS stateless mode with standard
WDS in the ath11k driver. NAWDS has shown incompatibility with WDS AP
and STA modes in ath11k, leading to issues like MAC address
duplication and unstable connections. By switching to standard WDS,
this patch aims to resolve these issues.

It also enables WDS backhaul in NSS for better handling of backhaul links.

Testing is still ongoing, but early results indicate improved
stability and fewer connection problems in affected environments
