Revert "usb: hub: Prevent hub autosuspend if usbcore.autosuspend is -1"

Certain USB-C devices are failing to enumerate if the bus
transitions from active to suspend between connection and enumeration.

When a USB-C accessory is inserted in a phone and is detected by the
CC lines, the controller driver is loaded and the only devices present
on the bus are the root hubs, until the device enumerations.
As a result, a suspend transition between device connection and
enumeration is very likely.

This change leaves the hub autosuspend set to the usbcore.autosuspend
value so a value can be set high enough to prevent this race.

This reverts:
commit bdd405d2a528 ("usb: hub: Prevent hub autosuspend if usbcore.autosuspend is -1")

  If user specifies that USB autosuspend must be disabled by module
  parameter "usbcore.autosuspend=-1" then we must prevent
  autosuspend of USB hub devices as well.

  commit 596d789a211d introduced in v3.8 changed the original behaivour
  and stopped respecting the usbcore.autosuspend parameter for hubs.
