From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>
Fix to return a negative error code in the vb2_dma_contig_init_ctx()
error handling case instead of 0, as done elsewhere in this function.
Also vb2_dma_contig_init_ctx() return ERR_PTR() in case of error and
never return NULL, so use IS_ERR() replace IS_ERR_OR_NULL().
