Subject: [PATCH for-next 06/10] RDMA/hns: Fix mismatch exception rollback

From: wenglianfa <wenglianfa@...wei.com>

When dma_alloc_coherent() fails in hns_roce_alloc_hem(), just call
kfree() to release hem instead of hns_roce_free_hem().

Fixes: c00743cbf2b8 ("RDMA/hns: Simplify 'struct hns_roce_hem' allocation")
