ms/fs: fix adding security options to statmount.mnt_opt
Prepending security options was made conditional on sb->s_op->show_options,
but security options are independent of sb options.
Fixes: 056d33137bf9 ("fs: prepend statmount.mnt_opts string with
security_sb_mnt_opts()")
Fixes: f9af549d1fd3 ("fs: export mount options via statmount()")
