rocker: fix incorrect error handling in dma_rings_init

Browse source 
[ Upstream commit 58d0c864e1a759a15c9df78f50ea5a5c32b3989e ]

In rocker_dma_rings_init, the goto blocks in case of errors
caused by the functions rocker_dma_cmd_ring_waits_alloc() and
rocker_dma_ring_create() are incorrect. The patch fixes the
order consistent with cleanup in rocker_dma_rings_fini().
