Subject: [PATCH] selinux: remove redundant msg_msg_alloc_security

From: Huaisheng Ye <yehs1@...ovo.com>

selinux_msg_msg_alloc_security only calls msg_msg_alloc_security but
do nothing else. And also msg_msg_alloc_security is just used by the
former.

Remove the redundant function to simplify the code.
