Julius Werner b59e8505d8 libpayload: usbmsc: Remove DETACHED state from MSC device structure ... The USB MSC device structure contains a "ready" state that can be either "ready", "not ready" or "detached". The last one can only be assigned when the device is completely unresponsive and gets forcefully logically detached via usb_detach_device(). This call (at least in the current version) also calls all destructors and frees the complete usbdev_t structure (including the MSC specific part), which unfortunately makes storing the "detached" state in that very structure a little pointless. This patch reduces the "ready" value to a simple boolean and makes sure that all detachment cases immediately return from the MSC driver, carefully avoiding any use-after-free opportunities.
