qcacld-3.0: update dump_tx_desc

The dump_tx_desc function is called to report the number of freed and used
tx descriptors when a suspend is rejected by data path.  The debug code
was directly referencing a data field whereas the code to check the freed
and used descriptors used a function that reports a different number under
certain compilation flags.  Use the function in the debug statement such that
the value checked is the value printed.
