RDMA/hns: Fix memory leak in free_mr_init()

Browse Source 
[ Upstream commit 288f535951aa81ed674f5e5477ab11b9d9351b8c ]

When a reserved QP fails to be created, the memory of the remaining
created reserved QPs is leaked.

Fixes: 70f9252158 ("RDMA/hns: Use the reserved loopback QPs to free MR before destroying MPT")
