net: percpu_counter_inc() should not be called in BH-disabled section
Based upon a lockdep report by Alexey Dobriyan.
I checked all per_cpu_counter_xxx() usages in network tree, and I
think all call sites are BH enabled except one in
inet_csk_listen_stop().
commit dd24c00191d5e4a1ae896aafe33c6b8095ab4bd1
(net: Use a percpu_counter for orphan_count)
replaced atomic_t orphan_count to a percpu_counter.
atomic_inc()/atomic_dec() can be called from any context, while
percpu_counter_xxx() should be called from a consistent state.
For orphan_count, this context can be the BH-enabled one.
