fsnotify: preserve 64-bit pre-content ranges
vfs_fallocate() and remap_verify_area() pass 64-bit lengths to
fsnotify_file_area_perm(), which truncates them to size_t on
32-bit systems.
Use 64 bit (unsigned) types throughout the entire pre-content
notification chain to keep the full range. The userspace range
field is already 64-bits.
Fixes: 9740d17162de ("fsnotify: pass optional file access range in pre-content event")
