[PATCH 1/2] net/mlx4_en: Remove dependency between timestamping capability and service_task

[Talat Batheesh]

From: Eugenia Emantayev <eugenia at mellanox.com>

Subject: [trusty] [PATCH 1/2] (upstream) Fixing PTP and timekeeper after reboot.

BugLink: http://bugs.launchpad.net/bugs/1537859

commit 90683061dd50b0d70f01466c2d694f4e928a86f3 upstream.

Service task is responsible for other tasks in addition to timestamping
overflow check. Launch it even if timestamping is not supported by device.

Fixes: 07841f9d94c1 ('net/mlx4_en: Schedule napi when RX buffers allocation fails')
