io_uring: allow non-fixed files with SQPOLL The restriction of needing fixed files for SQPOLL is problematic, and prevents/inhibits several valid uses cases. With the referenced files_struct that we have now, it's trivially supportable. Treat ->files like we do the mm for the SQPOLL thread - grab a reference to it (and assign it), and drop it when we're done. This feature is exposed as IORING_FEAT_SQPOLL_NONFIXED.
