mlx4: fix error path in drivers/net/mlx4/en_rx.c
this warning:
drivers/net/mlx4/en_rx.c: In function ‘mlx4_en_activate_rx_rings’:
drivers/net/mlx4/en_rx.c:412: warning: ‘err’ may be used uninitialized in this function
Triggers because 'err' is uninitialized in the following input
conditions: priv->rx_ring_num is zero and mlx4_en_fill_rx_buffers()
fails.
But even if ->rx_ring_num is nonzero, 'err' will be zero if
mlx4_en_fill_rx_buffers() fails and mlx4_en_activate_rx_rings() returns
success - incorrectly.
So it's best to keep the error code uptodate on mlx4_en_fill_rx_buffers()
calls as well.
