tty: 8250, remove shadow and unused variables
The compiler complains about variables that are set, but never used:
* intX variables in exar_handle_irq
drivers/tty/serial/8250/8250_port.c:1864:34: warning: variable ‘int3’ set but not used [-Wunused-but-set-variable]
* val variable in pci_quatech_wqopr
drivers/tty/serial/8250/8250_pci.c:1139:10: warning: variable ‘val’ set but not used [-Wunused-but-set-variable]
And about a shadow variable:
* tmout in wait_for_xmitr is defined twice with the same type. Both of
them are also initialized before use.
Remove all of them.
