scsi: tcmu: add module wide block/reset_netlink support
This patch based on Xiubo's patches adds 2 tcmu attr to block and reset the netlink interface. It's used during userspace daemon reinitialization after the daemon has crashed while there is outstanding nl requests. The daemon can block the nl interface, kill outstanding requests in the kernel and then reopen the netlink socket and unblock it to allow new requests.
