tun: fix build warnings
Stephen Rothwell reports a build warnings(powerpc ppc64_defconfig)
drivers/net/tun.c: In function 'tun_do_read.part.5':
/home/sfr/next/next/drivers/net/tun.c:1491:6: warning: 'err' may be
used uninitialized in this function [-Wmaybe-uninitialized]
int err;
This is because tun_ring_recv() may return an uninitialized err, fix this.
