[PATCH 13/18] staging/lustre/llite: Fix uninitialized variable

[Oleg Drokin]

From: Dmitry Eremin <dmitry.eremin@xxxxxxxxx>

'f.f_flags' might be used uninitialized in this function.

xattr.c:248: 'f.f_flags' is declared.
xattr.c:244: lump!= ( (void* )0) is true
xattr.c:254: 'f.f_flags' is used, but is uninitialized.
