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

Browse source

commit bdd405d2a5 upstream.

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 596d789a21 introduced in v3.8 changed the original behaivour
and stopped respecting the usbcore.autosuspend parameter for hubs.

Fixes: 596d789a21 "USB: set hub's default autosuspend delay as 0"
