qcacld-3.0: Remove unused typedef wma_txFailIndCallback

Previously change I7faaf646df363a74954defbef103afbb4b72af92
("qcacld-3.0: Add extended IBSS feature on qcacld-3.0") introduced two
different typedefs to serve the same purpose, txFailIndCallback which
is in use, and wma_txFailIndCallback which is unused, so remove the
unused one.
