[PATCH 42/66] i386/i386at/lpr.c: remove uninitialized variable

[Marin Ramesa]

Variable lpr_alive is never initialized. I suggest a removal of
the code that deals with this variable.

But, on the other hand, maybe the variable should be initialized
to all zero.

It's not so clear from the code.

* i386/i386at/lpr.c (lpr_alive): Remove variable.
Remove the if.
