net: hsr: Add support for MC filtering at the slave device 



When MC (multicast) list is updated by the networking layer due to a
user command and as well as when allmulti flag is set, it needs to be
passed to the enslaved Ethernet devices. This patch allows this
to happen by implementing ndo_change_rx_flags() and ndo_set_rx_mode()
API calls that in turns pass it to the slave devices using
existing API calls.
