MLK-11183 usb: chipidea: otg: complete state machine before cancel hrtimer When do usb driver module load and unload loop test for A-device, the hrtimer may be cancelled during otg state machine running, so after the hrtimer is cancelled, the otg state machine may start it again by adding a new timer, this will cause the hrtimer will be active after its function memory is freed by module unload. This patch is to fix it by trying to hold the fsm mutex lock before setting otg state to be undefined, then otg hrtimer will be cancelled after current otg fsm transition completes, and no new timer will be added.
