usb: storage: Add usb_stor_dbg, reduce object size
Reduce the size of the objects by consolidating
the duplicated USB_STORAGE into a single function.
Add function usb_stor_dbg to emit debugging messages.
Always validate the format and arguments.
Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG.
Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG
is set.
