net/ixgbe: fix hash handle leak

[ upstream commit 03f83d6 ]

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: 080e3c0 ("net/ixgbe: store flow director filter")
Fixes: d0c0c41 ("net/ixgbe: store L2 tunnel filter")
