[GFS2] Remove drop of module ref where not needed
[GFS2] Remove drop of module ref where not needed

In an earlier patch "[GFS2] fix file_system_type leak on gfs2meta mount"
we removed the code to grab a ref to the module which was not needed
(since we know that the module cannot be unloaded at that time) so
this patch removes the code to drop that reference.
