mxser: remove tty_port_tty_get from mxser_check_modem_status
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.
