Zhu Yanjun fd5382c580 RDMA/rxe: Fix error unwind in rxe_create_qp() 
In the function rxe_create_qp(), rxe_qp_from_init() is called to
initialize qp, internally things like the spin locks are not setup until
rxe_qp_init_req().

If an error occures 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.

Move the spinlock initializations earlier before any failures.

Fixes: 8700e3e7c4 ("Soft RoCE driver")
