[Tarantool-patches] [PATCH v12 3/8] request: add missing OutOfMemory diag_set

[Cyrill Gorcunov <gorcunov@gmail.com>]

In request_create_from_tuple and request_handle_sequence
we may be unable to request memory for tuples, don't
forget to setup diag error otherwise diag_raise will
lead to nil dereference.
