tty/amiserial: avoid interruptible_sleep_on
interruptible_sleep_on is generally problematic and we want to get
rid of it. In case of TIOCMIWAIT, that race is actually in user
space and does not get fixed since we can only detect changes after
entering the ioctl handler, but it removes one more caller.
This instance can not be trivially replaced with wait_event, so
I chose to open-code the wait loop using prepare_to_wait/finish_wait.
