Subject: [net V2 08/10] net/mlx5: Use recovery timeout on sync reset flow

From: Moshe Shemesh <moshe@...dia.com>

Use the same timeout for sync reset flow and health recovery flow, since
the former involves driver's recovery from firmware reset, which is
similar to health recovery. Otherwise, in some cases, such as a firmware
upgrade on the DPU, the firmware pre-init bit may not be ready within
current timeout and the driver will abort loading back after reset.
