UBIFS: fix compilation warning
Alexandre Pereira da Silva [Mon, 25 Jun 2012 20:47:49 +0000 (17:47 -0300)]
Fix the following compilation warning:

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 the 'uninitialized_var()' macro to get rid of this false-positive.

Artem: massaged the patch a bit.
