ipv6: Consider sk_bound_dev_if when binding a raw socket to an address
[ Upstream commit 72f7cfab6f93a8ea825fab8ccfb016d064269f7f ]
IPv6 does not consider if the socket is bound to a device when binding
to an address. The result is that a socket can be bound to eth0 and
then bound to the address of eth1. If the device is a VRF, the result
is that a socket can only be bound to an address in the default VRF.
Resolve by considering the device if sk_bound_dev_if is set.
