Revert "USB: hub: Don't record a connect-change event during reset-re…

…sume"

This reverts commit e5d078a.

On Pi 4, an upstream kernel change resulted in disconnect events not being
registered by the kernel when a suspended device was unplugged. Devices that
get autosuspended by default (hubs and webcams) would remain "stuck" in
the kernel's list of attached devices, leading to a nonresponsive port.

Reverting this commit fixes the issue.

See #3546
