selinux: access superblock_security_struct in LSM blob way
[ Upstream commit 0266c25e7c2821181b610595df42cbca6bc93cb8 ]
LSM blob has been involved for superblock's security struct. So fix the
remaining direct access to sb->s_security by using the LSM blob
mechanism.
Fixes: 08abe46b2cfc ("selinux: fall back to SECURITY_FS_USE_GENFS if no xattr support")
Fixes: 69c4a42d72eb ("lsm,selinux: add new hook to compare new mount to an existing mount")
