[PATCH] fsnotify: Add debug printing of target link

[Cyrill Gorcunov]

Suitable for debugging. Still I fear in multiprocess
restore procedure second pr_debug might be interrupted
by pr_debug from another task since the logging engine
supports only pr_ call granularity, not the sequence
of the pr_debug calls.
