qcacld-3.0: Pass the function name for control path skb allocation

Presently whenever the control path is allocating the skb it is
passing the filename rather than than the function name required
by the qdf nbuf framework which is not much useful since when the
absolute path of the filename is considered and that can be truncated
leaving with only linenumber to understand the issue.

Pass the function name so it would help in root-causing the issue.
