gfs2: Fix memory leak when gfs2meta's fs_context is freed
gfs2 and gfs2meta share an ->init_fs_context function which allocates an
args structure stored in fc->fs_private. gfs2 registers a ->free
function to free this memory when the fs_context is cleaned up, but
there was not one registered for gfs2meta, causing a leak.
Register a ->free function for gfs2meta. The existing gfs2_fc_free
function does what we need.
