[PATCH] usb: storage: fix infinite wait loop by incrementing loop counter

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

If jumpshot_get_status continues to return a failed result then the
wait loop will spin forever because the waitcount counter is never
being incremented and we don't ever timeout.  Fix this by incrementing
waitcount.
