[PATCH v7 4/6] net/core: apply pm_runtime_set_memalloc_noio on network devices

Deadlock might be caused by allocating memory with GFP_KERNEL in runtime_resume and runtime_suspend callback of network devices in iSCSI situation, so mark network devices and its ancestor as 'memalloc_noio' with the introduced pm_runtime_set_memalloc_noio(). Cc: "David S. Miller" Cc: Eric
