RDMA/rxe: Fix NULL-ptr-deref in rxe_qp_do_cleanup() when socket create failed

There is a null-ptr-deref when mount.cifs over rdma:

BUG: KASAN: null-ptr-deref in rxe_qp_do_cleanup+0x2f3/0x360 [rdma_rxe] Read of size 8 at addr 0000000000000018 by task mount.cifs/3046

The root cause of the issue is the socket create failed in rxe_qp_init_req().

So move the reset rxe_qp_do_cleanup() after the NULL ptr check.
