  9p: sysfs_init: don't hardcode error to ENOMEM (2025-09-27 21:44:38 +0900)

----------------------------------------------------------------
Bunch of unrelated fixes

- polling fix for trans fd that ought to have been fixed otherwise back
in March, but apparently came back somewhere else...
- USB transport buffer overflow fix
- Some dentry lifetime rework to handle metadata update for currently
opened files in uncached mode, or inode type change in cached mode
- a double-put on invalid flush found by syzbot
- and finally /sys/fs/9p/caches not advancing buffer and overwriting
itself for large contents

Thanks to everyone involved!
