usb: musb: host: fix potential NULL pointer dereference
[ Upstream commit 2b63f1329df2cd814c1f8353fae4853ace6521d1 ]
musb_start_urb() doesn't check the pass-in parameter if it is NULL. But
in musb_bulk_nak_timeout() the parameter passed to musb_start_urb() is
returned from first_qh(), which could be NULL.
So wrap the musb_start_urb() call here with a if condition check to
avoid the potential NULL pointer dereference.
Fixes: f283862f3b5c ("usb: musb: NAK timeout scheme on bulk TX endpoint")
