  The function ixgbe_fdir_filter_init() and ixgbe_l2_tn_filter_init()
could return errors, the return value need to be checked and returned.

Fixes: 080e3c0ee989 ("net/ixgbe: store flow director filter")
Fixes: d0c0c416ef1f ("net/ixgbe: store L2 tunnel filter")

The interrupt needs to be closed ?

ixgbe_disable_intr(hw);

rte_intr_disable(intr_handle);

rte_intr_callback_unregister(intr_handle, ixgbe_dev_interrupt_handler, eth_dev);
