RDMA/rxe: Fix the error caused by qp->sk

Browse Source 
[ 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.
