net/mlx5: LAG, drop stale esw_shared_ingress_acl gate from shared FDB

Browse Source 
The shared-FDB support check still requires the esw_shared_ingress_acl
capability. That capability backed the merged uplink ingress ACL, where
the slave uplink's ingress-ACL root was pointed at the master's
(esw_set_uplink_slave_ingress_root()). That handling was removed in
commit 82e86a6c71 ("net/mlx5: E-switch, remove special uplink ingress
ACL handling") once both uplinks were tagged with the same reserved
metadata (MLX5_ESW_METADATA_RSVD_UPLINK) - a single FDB rule then
matches traffic from either uplink, with no shared ingress ACL involved.

The capability check was left behind and has been dead since: the driver
programs no shared ingress ACL, yet the check still keeps otherwise
shared-FDB-capable devices out of shared FDB. Drop it.
