[v2,01/16] fanotify: don't skip extra event info if no info_mode is set

Commit Message

New pre-content events will be path events but they will also carry
additional range information. Remove the optimization to skip checking
whether info structures need to be generated for path events. This
results in no change in generated info structures for existing events.
