Subject: [PATCH net-next 08/11] mptcp: remove a list of addrs when flushing

From: Geliang Tang <geliangtang@...il.com>

This patch invoked mptcp_nl_remove_addrs_list to remove a list of addresses
when the netlink flushes addresses, instead of using
mptcp_nl_remove_subflow_and_signal_addr to remove them one by one.

And dropped the unused parameter net in __flush_addrs too.
