sfc: Use dev_kfree_skb() in efx_end_loopback()
Fix CID 102619 in the Coverity report on Linux.
efx_end_loopback() iterates over an array of skb pointers of which
some may be null (if efx_begin_loopback() failed). It should not use
dev_kfree_skb_irq(), which requires non-null pointers. In practice
this is safe because it does not run in interrupt context and
therefore always ends up calling dev_kfree_skb(), which does allow
null pointers. But we should make that explicit.
