[PATCH] Silence compiler warning

[Jim Rees <rees@umich.edu>]

I think this is still needed, isn't it?  I haven't tried compiling
nfs-for-next but I don't see a fix for it in there.

Subject: [PATCH] Silence compiler warning

fs/nfs/callback_proc.c: In function ‘do_callback_layoutrecall’:
fs/nfs/callback_proc.c:115:26: warning: ‘lo’ may be used uninitialized in this function

No functional change. If no layout is found, we'll return before  using
"lo".
