Konstantin Belousov bf0db19339 buf SU hooks: track buf_start() calls with B_IOSTARTED flag ... and only call buf_complete() if previously started. Some error paths, like CoW failire, might skip buf_start() and do bufdone(), which itself call buf_complete(). Various SU handle_written_XXX() functions check that io was started and incomplete parts of the buffer data reverted before restoring them. This is a useful invariant that B_IO_STARTED on buffer layer allows to keep instead of changing check and panic into check and return.
