Larry Finger 810b4de25e tty/serial/pmac_zilog: Fix "nobody cared" IRQ message 
Following commit a79dd5a titled "tty/serial/pmac_zilog: Fix suspend & resume",
my Powerbook G4 Titanium showed the following stack dump:

[   36.878225] irq 23: nobody cared (try booting with the "irqpoll" option)
[   36.878251] Call Trace:

From an E-mail exchange about this problem, Andreas Schwab noticed a typo
that resulted in the wrong condition being tested.

The patch also corrects 2 typos that incorrectly report why an error branch
is being taken.
