ipv4: fix a dst leak in tunnels
This patch :
1) Remove a dst leak if DST_NOCACHE was set on dst
Fix this by holding a reference only if dst really cached.
2) Remove a lockdep warning in __tunnel_dst_set()
This was reported by Cong Wang.
3) Remove usage of a spinlock where xchg() is enough
4) Remove some spurious inline keywords.
Let compiler decide for us.
