[PATCH] USB: gadget-serial: fix a deadlock when closing the serial device

When closing the device, the driver acquires/release twice the
port lock before/after waiting for the data to be completely
sent. Therefore it will dead lock.

This patch fixes it and also uses the generic scheduler services
for waiting for an event.
