eth: fbnic: put back netmem reference when xdp_buff_add_frag() fails

Browse source

fbnic_add_rx_frag() takes a page_pool reference out of the buffer's
pagecnt_bias before handing the fragment to xdp_buff_add_frag(). If that
call fails it has not taken ownership of the netmem: the fragment is not
recorded in the shared info, and fbnic_put_pkt_buff() will not put the
reference back.

Put the netmem reference back on the failure path.
