RDMA/rxe: Replace __rxe_do_task by rxe_run_task

In rxe_req.c replace calls to __rxe_do_task() by calls to rxe_run_task(..,
0). Using __rxe_do_task is an error because the completer tasklet is not
designed to be re-entrant and __rxe_do_task() should only be called when
it is clear that no one else could be calling the completer tasklet as is
the case in rxe_qp.c where this call is used in safe environments.
