Subject: [PATCH 3.18 091/144] net/mlx4_en: Remove dependency between timestamping capability and service_task

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit fc9f5ea9b4ecbe9b7839c92f0a54261809c723d3 ]

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')
