[IRDA]: Avoid a label defined but not used warning in irda_init()

Easily avoidable compiler warnings bug me.

Building irmod without CONFIG_SYSCTL currently results in :
 net/irda/irmod.c:132: warning: label 'out_err_2' defined but not used

But that can easily be avoided by simply moving the label inside
the existing "#ifdef CONFIG_SYSCTL" one line above it.

This patch moves the label and buys us one less warning with no
ill effects.
