musb-new: Fix interrupt transfers not working

For bulk and ctrl transfers common/usb.c sets udev->status = USB_ST_NOT_PROC,
but it does not do so for interrupt transfers.

musb_uboot.c: submit_urb() however was waiting for USB_ST_NOT_PROC to become 0,
and thus without anyone setting USB_ST_NOT_PROC would exit immediately for
interrupt urbs, returning the urb status of EINPROGRESS as error.

This commit fixes this, thereby also making usb_kbd.c work together with
musb_new and CONFIG_SYS_USB_EVENT_POLL.
