Serial number on some USB devices might exceed the number of 100 characters
(e.g. 120 characters on "SanDisk Ultra 3.2Gen1" pendrive) and cause buffer
overflow, resulting in usbstor.sys crash.
- Use pool allocation for instance ID generation.
Fixes stack overflow on USB storage devices with large serial number.
- Print the LUN number as a hexadecimal, not as a character.
- Verify the serial number descriptor before using it.
- Increase the max descriptor size for serial number to
MAXIMUM_USB_STRING_LENGTH. This fixes serial number string truncation.
