audit: widen ino fields to u64
inode->i_ino is being widened from unsigned long to u64. The audit
subsystem uses unsigned long ino in struct fields, function parameters,
and local variables that store inode numbers from arbitrary filesystems.
On 32-bit platforms this truncates inode numbers that exceed 32 bits,
which will cause incorrect audit log entries and broken watch/mark
comparisons.
Widen all audit ino fields, parameters, and locals to u64, and update
the inode format string from %lu to %llu to match.
