Xingxing Luo 33d7e37232 usb: musb: Get the musb_qh poniter after musb_giveback 
When multiple threads are performing USB transmission, musb->lock will be
unlocked when musb_giveback is executed. At this time, qh may be released
in the dequeue process in other threads, resulting in a wild pointer, so
it needs to be here get qh again, and judge whether qh is NULL, and when
dequeue, you need to set qh to NULL.

Fixes: dbac5d07d1 ("usb: musb: host: don't start next rx urb if current one failed")
