[PATCH] Cyclades: Avoid label defined but not used warning

[Jesper Juhl <jesper.juhl@gmail.com>]

Hi,

I don't like compiler warnings, especially not when they are easy to 
avoid.

Building cyclades driver without CONFIG_PCI currently results in this :

   CC      drivers/char/cyclades.o
 drivers/char/cyclades.c: In function 'cy_init':
 drivers/char/cyclades.c:5488: warning: label 'err_unr' defined but not used

That's easily avoided, with no ill effects by simply moving what's 
under the 'err_unr' label (used from only a single location) inside 
the existing #ifdef - so that's what this patch does.

Compile tested on i386 only. I don't have the hardware to do any 
other testing.

Please consider applying.
