Subject: [PATCH] net/mlx4: update link status upon probing with LSC

[ upstream commit 3fca2ab597d80dbb3052ec691342ca6a8e1e508b ]

If LSC interrupts are enabled, the application expects the link_update
ops to be executed by the PMD itself.

No link status change event is received upon probing, therefore the link
status update must be forced.

Fixes: c4da6caa426d ("mlx4: handle link status interrupts")
