smb: client: rework cached dirs synchronization
This patch adds usage of RCU and seqlocks for cached dir (list and
entries).
Traversing the list under RCU allows faster lookups (no locks) and also
guarantees that entries being read are not gone (i.e. prevents UAF).
seqlocks provides atomicity/consistency when reading entries, allowing
callers to re-check cfid in case of write-side invalidation.
Combined with refcounting, this new approach provides safety for
callers and flexibility for future enhancements.
