AppOps: Fix yet another deadlock

A = AppOpsService.this
B = PowerManagerService.mLock

Thread 1:
  AppOpsService.noteOperation() (lock A) ->
  PowerManagerService.isInteractive() (lock B)

Thread 2:
  PowerManagerService.acquireWakeLockInternal() (lock B) ->
  AppOpsService.startOperation() (lock A)

Move PowerManagerService.isInteractive() so that 'Thread 1' becomes:
  PowerManagerService.isInteractive() (lock and release B) ->
  AppOpsService.noteOperation() (lock A)
