Subject: [PATCH] Silence 'may be used uninitialized' warning in net/sunrpc/svc.c.

Current kernels warn about:
net/sunrpc/svc.c: In function '__svc_create_thread':
net/sunrpc/svc.c:593: warning: 'oldmask.bits[0u]' may be used uninitialized in this function

As far as I can see oldmask will be initialised to something in each
case it's used.
