[PATCH 30/39] staging/lustre/build: build error with gcc 4.7.0 20110509

From: Peng Tao
Date: Thu Nov 14 2013 - 11:41:37 EST


From: Dmitry Eremin <dmitry.eremin@xxxxxxxxx>

Fixed the error: 'tgt' and 'nf' may be used uninitialized in
this function. Also fixed comparison signed and unsigned
indexes.
