rndis_host: Add early_init function pointer to 'struct rndis_data'.

Function pointer is for 'subminidrivers' that need to do work on device
right after minidriver has initialized hardware.

For example, rndis_wlan setting device specific configuration parameters
with OID_GEN_RNDIS_CONFIG_PARAMETER right after rndis_host has
initialized hardware with RNDIS_INIT.
