ice: Remove two impossible branches on XDP Tx cleaning
The tagged commit started sending %XDP_TX frames from XSk Rx ring
directly without converting it to an &xdp_frame. However, when XSk is
enabled on a queue pair, it has its separate Tx cleaning functions, so
neither ice_clean_xdp_irq() nor ice_unmap_and_free_tx_buf() ever happens
there.
Remove impossible branches in order to reduce the diffstat of the
upcoming change.
Fixes: a24b4c6e9aab ("ice: xsk: Do not convert to buff to frame for XDP_TX")
