Subject: usb: serial: fix memory leak in generic driver
From: Johan Hovold <jhovold@xxxxxxxxx>
Fix a regression introduced by commit
715b1dc01fe44537e8fce9566e4bb48d6821d84b ("USB: usb_debug,
usb_generic_serial: implement multi urb write").
URB transfer buffer was never freed when using multi-urb writes.
Currently the only driver enabling multi-urb writes is usb_debug.
