qcacmn: Dump the rx reo queue descs in ddr

Add iwpriv option 34 to dump the reo rx h/w descs
in DDR for debugging. This cmd will first send cache
flush cmd to REO for all rx tids and invalidate the h/w
cache. Henceforth ensuring that the reo status tlvs and
the DDR values are in sync.
iwpriv wlan0 txrx_stats 34 0
Add fix to ensure bar frame with 2k jump err code is
processed correctly using the REO error code instead of the
REO push reason.
