Subject: [PATCH] [resend] Finally fix Logitech Quickcam for Notebooks Pro

Increase UVC_CTRL_STREAMING_TIMEOUT to fix initialization of
Logitech Quickcam for Notebooks Pro.
This fixes following error messages:
uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.
uvcvideo: Failed to query (129) UVC probe control : -110 (exp. 26).
uvcvideo: Failed to initialize the device (-5).
