ENGR00154703 usb-gadget: fix spin_lock recursion problem at SMP platform

- The spin_lock is at interrupt handler, so all code routines
using at interrupt handler are forbidden to hold spin_lock again
- Move the code which needs to be protected by spin_lock to workqueue,
and it will be called when workqueue is scheduled.
