net: ena: Flush XDP packets on error.

Browse Source 
[ Upstream commit 6f411fb5ca ]

xdp_do_flush() should be invoked before leaving the NAPI poll function
after a XDP-redirect. This is not the case if the driver leaves via
the error path (after having a redirect in one of its previous
iterations).

Invoke xdp_do_flush() also in the error path.
