ipv6: Take rcu_read_lock in __inet6_bind for mapped addresses
[ Upstream commit d4a7e9bb74b5aaf07b89f6531c080b1130bdf019 ]
I realized the last patch calls dev_get_by_index_rcu in a branch not
holding the rcu lock. Add the calls to rcu_read_lock and rcu_read_unlock.
Fixes: ec90ad334986 ("ipv6: Consider sk_bound_dev_if when binding a socket to a v4 mapped address")
