net: ti: icssg-prueth: Fix packet handling for XDP_TX
While transmitting XDP frames for XDP_TX, page_pool is
used to get the DMA buffers (already mapped to the pages)
and need to be freed/reycled once the transmission is complete.
This need not be explicitly done by the driver as this is handled
more gracefully by the xdp driver while returning the xdp frame.
__xdp_return() frees the XDP memory based on its memory type,
under which page_pool memory is also handled. This change fixes
the transmit queue timeout while running XDP_TX.
