Eric Dumazet 1f62c25f24 netlink: hold nlk->cb_mutex longer in __netlink_dump_start()

[ Upstream commit b5590270068c4324dac4a2b5a4a156e02e21339f ]

__netlink_dump_start() releases nlk->cb_mutex right before
calling netlink_dump() which grabs it again.

This seems dangerous, even if KASAN did not bother yet.

Add a @lock_taken parameter to netlink_dump() to let it
grab the mutex if called from netlink_recvmsg() only.
