net/mlx5: HWS, Fix table creation UID

[ Upstream commit 8a51507 ]

During table creation, caller passes a UID using ft_attr. The UID
value was ignored, which leads to problems when the caller sets the
UID to a non-zero value, such as SHARED_RESOURCE_UID (0xffff) - the
internal FT objects will be created with UID=0.
