fs: refuse fspick() on internal superblocks
There's a few instances where a internal superblock is reachable by
fspick(). Block that. graft_tree() and fsmount() already refuse them.
fanotify refuses mount and superblock marks on them for the same reason.
Fixes: cf3cba4a429b ("vfs: syscall: Add fspick() to select a superblock for reconfiguration")
