Michael Grzeschik 6946a52392 USB: xhci: fix U1/U2 handling for hardware with XHCI_INTEL_HOST quirk set 
commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760 upstream.

The commit 0472bf06c6fd ("xhci: Prevent U1/U2 link pm states if exit
latency is too long") was constraining the xhci code not to allow U1/U2
sleep states if the latency to wake up from the U-states reached the
service interval of an periodic endpoint. This fix was not taking into
account that in case the quirk XHCI_INTEL_HOST is set, the wakeup time
will be calculated and configured differently.

It checks for u1_params.mel/u2_params.mel as a limit. But the code could
decide to write another MEL into the hardware. This leads to broken
cases where not enough bandwidth is available for other devices:

usb 1-2: can't set config #1, error -28

This patch is fixing that case by checking for timeout_ns after the
wakeup time was calculated depending on the quirks.

Fixes: 0472bf06c6fd ("xhci: Prevent U1/U2 link pm states if exit latency is too long")
