Subject: [PATCH 2/3] Restrict definition of a label in kernel/module.c

In function 'load_module' in kernel/module.c, the label 'free_init'
is used if and only if both CONFIG_MODULE_UNLOAD and CONFIG_SMP are
defined. However, the label itself is defined unconditionally,
which may produce the following warning:

kernel/module.c:2291: warning: label 'free_init' defined but not used

This patch fixes the warning by moving the label definition under an
appropriate preprocessor construct.
