s3-printing: vfs_connect prior to driver/dfs IO

samba3.posix_s3.rpc.spoolss.driver fails with the xattr_tdb vfs module
loaded as a part of make test. The (now checked) create_directory() call
in move_driver_to_download_area() fails, uncovering another bug in the
printer driver upload code path.

move_driver_to_download_area() creates a new conn_struct for
manipulating files in [print$]. The VFS layer is plumbed through with
the call to create_conn_struct(), however SMB_VFS_CONNECT() is never
called. Many vfs modules expect state stored at connect time with
SMB_VFS_HANDLE_SET_DATA() to be available on any IO operation and fail
if this is not the case.

This fix adds a call to SMB_VFS_CONNECT() in create_conn_struct() prior
to IO.
