usb-synopsys-otg: ensure ep alloc fails when endpoint_count < MAX_EP_COUNT.

Browse Source 
Before, it would alloc the endpoint fine and then panic later due to out of range.
This ensures it falis at ep alloc time, and with a panic message that says
what's the actual problem: "no free endpoints available".
