simserial, bail out when request_irq fails

Without this, the code succeeds when the port is opened by root and we
get unwanted interrupts storm on the first key stroke.

Instead of that, tell the user we failed and that we won't continue. I
suppose, the code was copied from the serial layer where we may want
to change the irq number, so we must allow open even of the failing
port. This is not the case for this driver at all.
