[PATCH v2] ubifs: Fix build warning

[Alexandre Pereira da Silva]

Fix:
fs/ubifs/dir.c: In function 'ubifs_rename':
fs/ubifs/dir.c:972:15: warning: 'saved_nlink' may be used uninitialized
in this function

Use gcc uninitialized_var macro to avoid bogus warning

Signed-off-by: Alexandre Pereira da Silva <aletes.xgr@xxxxxxxxx>
---
Applies to v3.5-rc4

Changes since v1:
Use uninitialized_var macro
