Subject: [PATCH 5.16 0989/1039] vdpa/mlx5: Fix config_attr_mask assignment

From: Eli Cohen <elic@...dia.com>

commit e3137056e6dedee205fccd06da031a285c6e34f5 upstream.

Fix VDPA_ATTR_DEV_NET_CFG_MACADDR assignment to be explicit 64 bit
assignment.

No issue was seen since the value is well below 64 bit max value.
Nevertheless it needs to be fixed.

Fixes: a007d940040c ("vdpa/mlx5: Support configuration of MAC")
