[SERIAL] Fix oops when removing suspended serial port
A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
