ip6mr: Annotate access to mrt->mroute_do_{pim,assert,wrvifwhole}.
These fields in struct mr_table are updated in ip6_mroute_setsockopt()
under RTNL:
* mroute_do_pim
* mroute_do_assert (MRT6_PIM is under RTNL while MRT6_ASSERT is lockless)
* mroute_do_wrvifwhole
However, ip6_mroute_getsockopt() does not hold RTNL and read the first
two fields locklessly, and ip6_mr_forward() reads all the three under
RCU.
Let's use WRITE_ONCE() and READ_ONCE() for them.
