usb: gadget: rndis: Fix re-binding f_rndis
f_rndis checks if rndis_string_defs[0].id is null to setup rndis and allocate string ids when it is bound to the first configuration: /* maybe allocate device-global string IDs */ if (rndis_string_defs[0].id == 0) { /* ... and setup RNDIS itself */ status = rndis_init(); if (status < 0) return status; rndis_string_defs[0].id must be reset to 0 on unbind for rndis to be correctly initialized on the next composite_bind.
