Dan Carpenter 3e62cbb843 smack: opt_dentry is never null in in smack_d_instantiate()
This patch removes some unneeded code for if opt_dentry is null because
that can never happen.

The function dereferences "opt_dentry" earlier when it checks
"if (opt_dentry->d_parent == opt_dentry) {".  That code was added in
2008.

This function called from security_d_instantiate().  I checked all the
places which call security_d_instantiate() and dentry is always non-null.
I also checked the selinux version of this hook and there is a comment
which says that dentry should be non-null if called from
d_instantiate().
