netlink: convert netlink tap spinlock to mutex
Both netlink_add_tap() and netlink_remove_tap() are called in process context, no need to bother spinlock. Note, in fact, currently we always hold RTNL when calling these two functions, so we don't need any other lock at all, but keeping this lock doesn't harm anything.
