[PATCH net 3/3] net/mlx5e: Do not fail PSP init on missing caps

[Tariq Toukan <tariqt@nvidia.com>]

From: Cosmin Ratiu <cratiu@nvidia.com>

PSP support requires a set of cap bits to be set, otherwise an init
error is logged.

But logging an error when PSP cannot be initialized is too much, and not
in line with other features. If a feature cannot be initialized because
it is not supported, that's not an error. An error should only be
printed when the feature cannot be initialized because of an actual
error.

Fixes: 89ee2d92f66c ("net/mlx5e: Support PSP offload functionality")
