RDMA/hns: Fix double free of the pointer to TSQ/TPQ

Browse Source 
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: d6d91e4621 ("RDMA/hns: Add support for configuring GMV table")
