[PATCH][SMB3] do not try to cache root directory if dir leases not supported
smfrench at gmail.com

To servers which do not support directory leases (e.g. Samba)
it is wasteful to try to open_shroot (ie attempt to cache the
root directory handle). Skip attempt to open_shroot when
server does not indicate support for directory leases.
Cuts the number of requests on mount from 17 to 15, and
cuts the number of requests on stat of the root directory
from 4 to 3.
(also added cc: stable v5.1+)
