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.
