Zhu Yanjun b2b1ddc457 RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task"
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like rxe_init_task are not setup until
rxe_qp_init_req().

If an error occurred before this point then the unwind will call
rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task()
which will oops when trying to access the uninitialized spinlock.

If rxe_init_task is not executed, rxe_cleanup_task will not be called.
