Subject: [PATCH for-next] RDMA/core/sa_query: Remove unused function
ib_sa_service_rec_query() was introduced in kernel v2.6.13 by commit
cbae32c56314 ("[PATCH] IB: Add Service Record support to SA client")
in 2005. It was not used then and have never been used since.
Removing it.

- * ib_sa_service_rec_query - Start Service Record operation
- * @client:SA client
- * @device:device to send request on
- * @port_num: port number to send request on
- * @method:SA method - should be get, set, or delete
- * @rec:Service Record to send in request
- * @comp_mask:component mask to send in request
- * @timeout_ms:time to wait for response
- * @gfp_mask:GFP mask to use for internal allocations
- * @callback:function called when request completes, times out or is
- * canceled
- * @context:opaque user context passed to callback
- * @sa_query:request context, used to cancel request
- *
- * Send a Service Record set/get/delete to the SA to register,
- * unregister or query a service record.
- * The callback function will be called when the request completes (or
- * fails); status is 0 for a successful response, -EINTR if the query
- * is canceled, -ETIMEDOUT is the query timed out, or -EIO if an error
- * occurred sending the query. The resp parameter of the callback is
- * only valid if status is 0.
- *
- * If the return value of ib_sa_service_rec_query() is negative, it is an
- * error code. Otherwise it is a request ID that can be used to cancel
- * the query.
