Amir Goldstein 8631e01c2c fanotify: sanitize handle_type values when reporting fid 
Unlike file_handle, type and len of struct fanotify_fh are u8.
Traditionally, filesystem return handle_type < 0xff, but there
is no enforecement for that in vfs.

Add a sanity check in fanotify to avoid truncating handle_type
if its value is > 0xff.

Fixes: 7cdafe6cc4 ("exportfs: check for error return value from exportfs_encode_*()")
