[ Upstream commit aded5d1feb08e48d544845d3594d70c4d5fe6e54 ]

Receive SKBs can go through the VF-rep path or the normal path.
skb_mark_for_recycle() is only called for the normal path.  Fix it
to do it for both paths to fix possible stalled page pool shutdown
errors.

Fixes: 86b05508f775 ("bnxt_en: Use the unified RX page pool buffers for XDP and non-XDP")
