Remove failure_count_ to simplify the code.
Remove failure_count_ to simplify the code.

Since |timer_| is one-shot, it seems that the failure counter is reset to zero almost every time and unlikely exceeds kMaxRetries (see issue 8096.)

I don't think we should implement another type of limiter since the on-demand ibus loading code is stable. Let's just remove failure_count_ and related logic.

BUG=none
TEST=manually tested that the flush function works fine without the counter.
