Eric Dumazet c2b226f223 netlink: convert nlk->flags to atomic flags

[ Upstream commit 8fe08d70a2b61b35a0a1235c78cf321e7528351f ]

sk_diag_put_flags(), netlink_setsockopt(), netlink_getsockopt()
and others use nlk->flags without correct locking.

Use set_bit(), clear_bit(), test_bit(), assign_bit() to remove
data-races.
