RDMA/hns: Fix mismatch exception rollback 

maillist inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9HASN
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc3bda6e568e9310b7cd07769dd70a3f0cd696ca



----------------------------------------------------------------------

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")
