Properly set the property_context for net.tcp_init_rwnd.
This property is many years old and it does not have a property
context associated with it. It is set by the system server (in
particular, ConnectivityService code, in the Tethering module)
and read by init, which does:
on property:net.tcp_def_init_rwnd=*
write /proc/sys/net/ipv4/tcp_default_init_rwnd ${net.tcp_def_init_rwnd}
There is no need to add read access to init because init can read
and write any property.
