Fix drop key stroke
Keyboard report should be checked if its transfer finishs successfully. Otherwise key stroke can be missing when other key event occurs before the last report transfer is done. Boot protocol 10ms interval probably causes this problem in case it receives key events in a row within the period. NKRO protocol suffers less or nothing due to its interval 1ms.tags/v2.9
