usb: xhci: relocate Restore/Controller error check

A Restore Error or Host Controller Error indicates that the host controller
failed to resume after suspend. In such cases, the xhci driver is fully
re-initialized, similar to a post-hibernation scenario.

The existing error check is only relevant when 'power_lost' is false.
If 'power_lost' is true, a Restore or Controller error has no effect:
no warning is printed and the 'power_lost' state remains unchanged.

Move the entire error check into the if '!power_lost' condition
to make this dependency explicit and simplify the resume logic.
