RDMA/rxe: Fix the error caused by qp->sk
[ Upstream commit 548ce2e66725dcba4e27d1e8ac468d5dd17fd509 ]
When sock_create_kern in the function rxe_qp_init_req fails,
qp->sk is set to NULL.
Then the function rxe_create_qp will call rxe_qp_do_cleanup
to handle allocated resource.
Before handling qp->sk, this variable should be checked.
Fixes: 8700e3e7c485 ("Soft RoCE driver")
