[PATCH] v9fs: make copy of the transport prototype instead of using it directly 

When a new session is created it uses a template object of the specified
transport type to instantiate its own copy.  The code for the making a copy of
the template object was lost, and the object itself is attached to the v9fs
session.  This leads to many sessions using the same transport instead of
having their own copy.

The patch puts back the code that makes a copy of the template object.
