net/ixgbe: check filter init failure

[ upstream commit 8c1e5c658c24553d5f813adc8afed8910e6f5194 ]

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