[PATCH 4/6] tcmu: misc nl code cleanup

[Mike Christie <mchristi@redhat.com>]

Some misc cleanup of the nl rework patches.

1. Fix space instead of tabs use and extra newline.
2. Drop initializing variables to 0 when not needed
3. Just pass the skb_buff and msg_header pointers to
tcmu_netlink_event_send.
