Subject: [08/23] net: treewide use of RCU_INIT_POINTER

commit 2cfa5a0471fef43fda0b7bd87e3a5e4dbadb7809 upstream.

rcu_assign_pointer(ptr, NULL) can be safely replaced by
RCU_INIT_POINTER(ptr, NULL)

(old rcu_assign_pointer() macro was testing the NULL value and could
omit the smp_wmb(), but this had to be removed because of compiler
warnings)
