qcacld-3.0: Remove session_id from nan_datapath_peer_ind (Step 2)

Currently struct nan_datapath_peer_ind contains the following:
	uint8_t session_id;

This is problematic since "session_id" is a legacy concept and should
not be used in the converged project. Fortunately this field does not
actually serve any purpose. But in order to cleanly remove it a 3-step
approach is required.

Step 1 (qcacld Change If6cf48ccbfe87b23b275720df51c6cc26af9fa5e):
Remove the logic from the converged NAN code which currently reads
this field and logs the value.

Step 2 (this change):
Remove the logic from the legacy NAN code which sets this field.

Step 3 (qcacld Change Ibeb8007c96ae1a902bfd7dd99a42ba4a291a1dc6):
Remove the session_id field from struct nan_datapath_peer_ind.
