usb: gadget: rndis: remove the limit of available rndis connections
RNDIS function has a limitation on the number of allowed instances. So far it has been RNDIS_MAX_CONFIGS, which happens to be one. In order to eliminate this kind of arbitrary limitation we should not preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params instances but instead allow allocating them on demand. This patch allocates struct rndis_params on demand in rndis_register(). Coversly, the structure is free()'d in rndis_deregister(). If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which is the same behaviour as before, but the moment of creation is delayed until struct rndis_params is actually allocated. rnids_init() and rndis_exit() have nothing to do, so they are eliminated.
