[PATCH 2/2] usb: xhci: fix timeout for transition from RExit to U0

From: Aaron Ma
Date: Sun Oct 21 2018 - 13:09:07 EST


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.
