mlx4: allow device removal by fixing dma unmap size
After opening the network interface, Mellanox ConnectX device cannot be
removed by hotplug because it has not properly unmapped all DMA memory.
It happens that mlx4_en_activate_rx_rings overrides the variable that
keeps the size of the memory mapped.
This is fixed by passing to mlx4_en_destroy_rx_ring the same size that is
given to mlx4_en_create_rx_ring.
After applying this patch, hot unplugging the device works after opening
the interface.
