Fix match_server check to allow for auto dialect negotiate
When using multidialect negotiate (default or specifying vers=3.0 which allows any smb3 dialect), fix how we check for an existing server session. Before this fix if you mounted a second time to the same server (e.g. a different share on the same server) we would only reuse the existing smb session if a single dialect were requested (e.g. specifying vers=2.1 or vers=3.0 or vers=3.1.1 on the mount command). If a default mount (e.g. not specifying vers=) is done then would always create a new socket connection and SMB3 (or SMB3.1.1) session each time we connect to a different share on the same server rather than reusing the existing one.
