ima: annotate iint mutex to avoid lockdep false positive warnings
commit e044374 upstream. It is not clear that IMA should be nested at all, but as long is it measures files both on overlayfs and on underlying fs, we need to annotate the iint mutex to avoid lockdep false positives related to IMA + overlayfs, same as overlayfs annotates the inode mutex.
