Subject: [PATCH net-next v2] net/mlx5e: Fix uninitialised struct field moder.comps

From: Yunjian Wang <wangyunjian@...wei.com>

The 'comps' struct field in 'moder' is not being initialized in
mlx5e_get_def_rx_moderation() and mlx5e_get_def_tx_moderation().
So initialize 'moder' to zero to avoid the issue.

Addresses-Coverity: ("Uninitialized scalar variable")
Signed-off-by: Yunjian Wang <wangyunjian@...wei.com>

v2: update mlx5e_get_def_tx_moderation() also needs fixing
