net: reintroduce missing rcu_assign_pointer() calls
[ Upstream commit cf778b00e96df6d64f8e21b8395d1f8a859ecdc7 ]
commit a9b3cd7f32 (rcu: convert uses of rcu_assign_pointer(x, NULL) to
RCU_INIT_POINTER) did a lot of incorrect changes, since it did a
complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x,
y).
We miss needed barriers, even on x86, when y is not NULL.
