serial: mps2-uart: Add parentheses around conditional in mps2_uart_shutdown
Clang warns:
drivers/tty/serial/mps2-uart.c:351:6: warning: logical not is only
applied to the left hand side of this bitwise operator
[-Wlogical-not-parentheses]
if (!mps_port->flags & UART_PORT_COMBINED_IRQ) {
^ ~
drivers/tty/serial/mps2-uart.c:351:6: note: add parentheses after the
'!' to evaluate the bitwise operator first

drivers/tty/serial/mps2-uart.c:351:6: note: add parentheses around left
hand side expression to silence this warning

As it was intended for this check to be the inverse of the one at the
bottom of mps2_init_port, add parentheses around the whole conditional.
