Felipe Moura d1418d9420 drivers/usbdev/cdcacm: fix self-deadlock in cdcuart_txempty() 
cdcuart_txempty() held priv->lock across EP_POLL(), which re-enters the
class through cdcacm_wrcomplete() and takes that same non-recursive lock,
and then took it a second time to read nwrq. Release it after the
disconnected check, matching cdcuart_txready()/cdcuart_rxavailable().

Fixes: cc067ab199 ("drivers/usbdev/cdcacm.c: Use small lock to protect cdcacm")
