usb: hub: Don't disable LPM completely if device initiated LPM fails
Enabling device initiated USB3 link power management (LPM) may fail for various reasons such as too long system exit latency, or link issues. These are not good reason to disable hub initiated LPM U1/U2 states, especially as it requires sending more requests over a possibly broken link, causing the hub work to block for even longer.
