[apparmor] [PATCH] apparmor: mv get_loaddata_common_ref() into CONFIG_SECURITY_APPARMOR_EXPORT_BINARY block

[yaolu]

From: Lu Yao <ya...@kylinos.cn>

When SECURITY_APPARMOR_EXPORT_BINARY is not set, the compiler emits an
unused-function warning which is promoted to an error with -Werror:
  security/apparmor/apparmorfs.c:177:28: error: ‘get_loaddata_common_ref’ 
defined but not used [-Werror=unused-function]

Move the function into the #ifdef block to match its only call site,
silencing the warning.

Fixes: 8e135b8aee5a ("apparmor: fix race between freeing data and fs accessing 
it")
Reported-by: k2ci <kernel-...@kylinos.cn>
