There are two capabilities related to CRC stripping:
1. mlx4 HW capability to perform CRC stripping on a recieved packet.
This capability is built in mlx4 HW. It should be returned by the API
call mlx4_get_rx_queue_offloads().
2. mlx4 driver capability to enable/disable HW CRC stripping. This
capability is dependent on the driver version.
Before this commit the seccond capability was falsely returned by
the mentioned API. This commit fixes it by returning the first
capability.
