usb: gadget: remove useless parameter in alloc_ep_req()
The default_length parameter of alloc_ep_req was not really necessary
and gadget drivers would almost always create an inline function to pass
the same value to len and default_len.
This patch removes that parameter and updates all calls to alloc_ep_req() to
use the new API.
