net/mlx5e: Set port trust mode to PCP as default
[ Upstream commit 2e8e70d249e8c5c79bf88bbb36bb68154ab15471 ]
The hairpin offload code has dependency on the trust mode being PCP.
Hence we should set PCP as the default for handling cases where we are
disallowed to read the trust mode from the FW, or failed to initialize it.
Fixes: 106be53b6b0a ('net/mlx5e: Set per priority hairpin pairs')
