Xiaoliang Pang 44c232fb52 cypto: mediatek - fix leaks in mtk_desc_ring_alloc 
[ Upstream commit 228d284aac61283cde508a925d666f854b57af63 ]

In the init loop, if an error occurs in function 'dma_alloc_coherent',
then goto the err_cleanup section, after run i--,
in the array ring, the struct mtk_ring with index i will not be released,
causing memory leaks
