There are various bits of code here that are unfinished and instead of
being harmless either confuse or spew stuff into the logs at higher than
debug level. They can and should go away.

Also remove the bogus use of tty->lowlatency. We fixed the need for this hack
long ago (with the flip buffer rewrite) but people keep copying it into drivers.

mxser_check_modem_status is called with tty parameter, so the
reference should be increased by callers already -- for ioctl
syscall it is held whole time gap since open to close, for
interrupt, the reference count is increased in the irq handler.

There is no tty_kref_put in that function, so this also fixes
a refcounting bug.
