RDMA\/rtrs-srv: Fix integer underflow in process_read and process_write<\/p>\n

Fix by reading and validating usr_len <= off before rtrs_srv_get_ops_ids()
\nin both process_read() and process_write(), ensuring the early return
\npath acquires no reference and has no resource leak.<\/p>\n","protected":false},"excerpt":{"rendered":"
