Subject: [PATCH 4.14 22/27] SMB3: Honor persistent/resilient handle flags for multiuser mounts

From: Paul Aurich <paul@...krain42.org>

commit 00dfbc2f9c61185a2e662f27c45a0bb29b2a134f upstream.

Without this:

- persistent handles will only be enabled for per-user tcons if the
  server advertises the 'Continuous Availabity' capability
- resilient handles would never be enabled for per-user tcons
