After detecting file system corruption and degrading to a read-only mount, dirty folios and buffers in the page cache are cleared, and a large number of warnings are output at that time, often filling up the kernel log. In this case, since the degrading to a read-only mount is output to the kernel log, these warnings are not very meaningful, and are rather a nuisance in system management and debugging. The related nilfs2-specific page/folio routines have a silent argument that suppresses the warning output, but since it is not currently used meaningfully, remove both the silent argument and the warning output.
