serial: stm32: use port lock wrappers for break control

Commit 30e945861f3b ("serial: stm32: add support for break control")
added another usage of the port lock, but was merged on the same day as
c5d06662551c ("serial: stm32: Use port lock wrappers"), therefore the
latter did not update this usage to use the port lock wrappers.

Fixes: c5d06662551c ("serial: stm32: Use port lock wrappers")
