net: ravb: Stop DMA in case of failures on ravb_open()
[ Upstream commit eac16a733427ba0de2449ffc7bd3da32ddb65cb7 ]
In case ravb_phy_start() returns with error the settings applied in
ravb_dmac_init() are not reverted (e.g. config mode). For this call
ravb_stop_dma() on failure path of ravb_open().
