 If dentry->d_name.len < EFI_VARIABLE_GUID_LEN , 'guid' can become negative, leadings to oob. The issue can
 be triggered by parallel lookups using invalid filename: T1 T2 lookup_open ->lookup simple_lookup d_add //
 invalid dentry is added to hash list lookup_open d_alloc_parallel __d_lookup_rcu __d_lookup_rcu_op_compare
 hlist_bl_for_each_entry_rcu // invalid dentry can be retrieved ->d_compare efivarfs_d_compare // oob Fix
 it by checking 'guid' before cmp. (CVE-2025-39817)
