GONG, Ruiqi 0266c25e7c selinux: access superblock_security_struct in LSM blob way ...

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: 08abe46b2c ("selinux: fall back to SECURITY_FS_USE_GENFS if no xattr support")
Fixes: 69c4a42d72 ("lsm,selinux: add new hook to compare new mount to an existing mount")
