CIFS: Fix endian conversion of vcnum field

commit 051a2a0d3242b448281376bb63cfa9385e0b6c68 upstream.

When multiply mounting from the same client to the same server, with
different userids, we create a vcnum which should be unique if
possible (this is not the same as the smb uid, which is the handle
to the security context).  We were not endian converting additional
(beyond the first which is zero) vcnum properly.
