usb: musb: fix DMA for host mode
Commit ac33cdb16681 ("usb: musb: Remove ifdefs for musb_host_rx in
musb_host.c part5") introduces a problem setting DMA host mode.
The musb_advance_schedule() is called immediately after receiving an
endpoint RX interrupt without waiting for the DMA transfer to complete.
As a consequence when the dma complete interrupt arrives the in_qh
member of hw_ep is already null an the musb_host_rx() exits on !urb
error case. Fix the done condition that advances the musb schedule.
