Sascha Hlusiak 2d85289225 sit: fix off-by-one in ipip6_tunnel_get_prl
[ Upstream commit 298bf12ddb25841804f26234a43b89da1b1c0e21 ]

When requesting all prl entries (kprl.addr == INADDR_ANY) and there are
more prl entries than there is space passed from userspace, the existing
code would always copy cmax+1 entries, which is more than can be handled.

This patch makes the kernel copy only exactly cmax entries.
