proc: introduce proc_create_net_single
Variant of proc_create_data that directly take a seq_file show callback and deals with network namespaces in ->open and ->release. All callers of proc_create + single_open_net converted over, and single_{open,release}_net are removed entirely. Signed-off-by: Christoph Hellwig <hch@lst.de>
