- fix bug when unplugged unmounted-already device (mostly plugged when power on)

- add hal_debugger_is_attached & hal_debugger_breakpoint
- assert will suspend (place breakpoint) if the condition is failed and debugger is attached. Otherwise, a message to uart is printed
- fix get control qhd function when dev_addr is not zero (shifted 1)
- fix wrong logic for unsupported class
