USB storage count
Here's another USB storage patch. Currently U-Boot handles storage devices #0 - #4 as valid devices, even if there is none connected. This patch fixes usb_stor_get_dev() to check detected device count instead of MAX-define. This is very important for ill behaving devices. usb_dev_desc[] can be partially initialized if device probe fails. After fixing get_dev() it was easy to fix "usb part" etc commands. Previously it outputed "Unknown partition table" five times, now it's "no USB devices available". Signed-off-by: Kim B. Heino <Kim.Heino@bluegiga.com>
