[CRIU] [PATCH v5 12/21] unix: Print reverted dir info if only directory provided

[Cyrill Gorcunov]

Otherwise there is an imbalance in logs with number of
"Reverted working dir" message

 | (00.018604)     36: unix: Connected 0x11ceff -> 0x11cf00 (0x11cf00) flags 0
 | (00.018644)     36: unix: Reverted working dir
 | (00.018652)     36: unix: Connected 0x11cefd -> 0x11cefe (0x11cefe) flags 0
 | (00.018665)     36: unix: Reverted working dir
 | (00.018688)     36: unix: Reverted working dir
