fuse: verify attributes
commit eb59bd17d2fa6e5e84fba61a5ebdea984222e6d5 upstream.
If a filesystem returns negative inode sizes, future reads on the file were
causing the cpu to spin on truncate_pagecache.
Create a helper to validate the attributes. This now does two things:
- check the file mode
- check if the file size fits in i_size without overflowing
