From: Leon Romanovsky <leonro@nvidia.com>

[ Upstream commit 907af0f0cab4ee5d5604f182ecec2c5b5119d294 ]

mlx5 firmware expects driver version in specific format X.X.X, so
make it always correct and based on real kernel version aligned with
the driver.

Fixes: 012e50e109fd ("net/mlx5: Set driver version into firmware")
