CVE:NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7af80c02c7b3cf7ac580a33f15d155730574769f

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

A return statement is omitted after getting HEM table, then the newly
allocated pointer will be freed directly, which will cause a calltrace
when the driver was removed.

Fixes: d6d91e46 ("RDMA/hns: Add support for configuring GMV table")
