USB: remove short initial timeout for device descriptor fetch
This patch (as905) removes a micro-optimization from the hub port
initialization code. Previously we had been using a short timeout on
the first attempt the read the device descriptor; now we will use the
standard timeout length.
It's not clear that the short timeout ever provided any benefit. And
now we know of one case where it actually hurts: The device can't meet
the short timeout and then it gets terminally confused.
This fixes Bugzilla #8444.
