media: mfc: skip idle suspend when mfc power is off
The idle worker timing issue still occur after we used del_timer_sync()
for mfc_idle_timer. The reason still unknown and it is not easy to
reproduce. To solve this issue I add an error handling that skip calling
idle suspend function when mfc power is off.
Bug: 325729612
Test: pause/resume/close all mfc components
