Subject: [net-next 02/15] net/mlx5: DR, Remove unneeded check from source port builder

From: [email-masked]
Date: Wed, 30 Sep 2020 21:32:49 -0700

From: Yevgeny Kliteynik <[email-masked]>

Mask validity for ste builders is checked by mlx5dr_ste_build_pre_check
during matcher creation.
It already checks the mask value of source_vport, so removing
this duplicated check.
Also, moving there the check of source_eswitch_owner_vhca_id mask.
