smb: client: short-circuit in open_cached_dir_by_dentry() if !dentry

When dentry is NULL, the current code acquires the spinlock and traverses
the entire list, but the condition (dentry && cfid->dentry == dentry)
ensures no match will ever be found.

Return -ENOENT early in this case, avoiding unnecessary lock acquisition
and list traversal.
