net/ixgbe: fix hash handle leak

In the ixgbe_fdir_filter_init and ixgbe_l2_tn_filter_init functions,
after the hash handle is created, the handle is not released in
subsequent abnormal branches.

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