net/mlx5/linux: fix firmware version

[ upstream commit 520e3f4 ]

This patch fixes a bug where firmware version was not
copied from ibv_device_attr structure into mlx5_dev_attr
structure, resulting in inability to read firmware
version.

Fixes: e85f623 ("net/mlx5: remove attributes dependency on Verbs")
