staging: lustre: llite: remove directory-specific code from ll_find_alias()

}

/*

 * try to reuse three types of dentry:

 * 1. unhashed alias, this one is unhashed by d_invalidate (but it may be valid

 *    by concurrent .revalidate).

 * 2. INVALID alias (common case for no valid ldlm lock held, but this flag may

 *    be cleared by others calling d_lustre_revalidate).

 * 3. DISCONNECTED alias.

 * Try to reuse unhashed or invalidated dentries.
