Windows SMBFS: avoid mounting local shares by default 

In quite a few situations, SMB shares exposed by the local server
cannot be mounted locally (e.g. SoFS shares).

The Nova Hyper-V driver will always pass the 'local_path_for_loopback'
flag to the os-brick connector, but this doesn't happen when Cinder
connects to volumes exposed by the SMB driver. For this reason,
cinder will fail to backup volumes residing on SoFS shares.

To keep it simple, we can just change the default behavior of the SMB
os-brick connector so that local shares are never mounted, using the
shared path directly.
