[GFS2] fix file_system_type leak on gfs2meta mount
get_gfs2_sb does a get_fs_type without doing a put_filesystem and thus leaking a file_system_type reference everytime it's called. Just use gfs2_fs_type directly instead of doing the lookup and thus fix the problem. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
