Kuniyuki Iwashima 2b260dc923 net: Add net_passive_inc() and net_passive_dec(). ...

[ Upstream commit e57a632021 ]

net_drop_ns() is NULL when CONFIG_NET_NS is disabled.

The next patch introduces a function that increments
and decrements net->passive.

As a prep, let's rename and export net_free() to
net_passive_dec() and add net_passive_inc().
