USB: core: Tolerate protocol stall during hub and port status read
commit 3824c1ddaf744be44b170a335332b9d6afe79254 upstream.
Protocol stall should not be fatal while reading port or hub status as it is
transient state. Currently hub EP0 STALL during port status read results in
failed device enumeration. This has been observed with ST-Ericsson (formerly
Philips) USB 2.0 Hub (04cc:1521) after connecting keyboard.
