erofs: use kill_anon_super() to kill super in fscache mode 

[ Upstream commit 1015c1016c ]

Use kill_anon_super() instead of generic_shutdown_super() since the
mount() in erofs fscache mode uses get_tree_nodev() and associated
anon bdev needs to be freed.

Fixes: 9c0cc9c729 ("erofs: add 'fsid' mount option")
