lsm: constify 'sb' parameter in security_sb_kern_mount()

Browse Source 
The "sb_kern_mount" hook has implementation registered in SELinux.
Looking at the function implementation we observe that the "sb"
parameter is not changing.

Mark the "sb" parameter of LSM hook security_sb_kern_mount() as "const"
since it will not be changing in the LSM hook.
