usb: xhci: fix timeout for transition from RExit to U0
commit a5baeaeabcca3244782a9b6382ebab6f8a58f583 upstream.
This definition is used by msecs_to_jiffies in milliseconds.
According to the comments, max rexit timeout should be 20ms.
Align with the comments to properly calculate the delay.
Verified on Sunrise Point-LP and Cannon Lake.
