staging: serqt_usb2: remove retval initialisation in qt_tiocmget and qt_tiocmset
in qt_tiocmset, the retval gets assigned if we have a valid serial pointer in the critical section (between mutex_lock and _unlock) of the code, no need to initialise this variable. the same retval assignment follows in the qt_tiocmget function also, so remove the initialisation here too.
