qlnx: qlnxe: Fix kernel address leakage
In function qlnx_rdma_deregister_if,
the address of object rdma_if will be printed out.
rdma_if is the address of a global variable qlnxr_drv,
which is passed from dev/qlnx/qlnxr/qlnxr_os.c
A kernel address leakage happens.
Fix this by removing the printf statement.
