When removing SD card from USB card reader, the USB MSC stack does
not detach the device immediately. Instead, the USB MSC stack calls
usbdisk_remove() and calls usb_msc_destroy() after several pollings.
It results in usbdisk_remove() being called twice.
Since the usbmsc_inst_t instance is freed after first usbdisk_remove()
call, the second call invokes an invalid usbmsc_inst_t instance and
causes exception in CPU.
This patch prevents usbdisk_remove() from being called twice by setting
usbdisk_created to zero.
BUG=b:239492347
TEST=insert an empty SD card into the USB card reader then remove
the SD card. AP firmware does not crash.
