fuse: validate folio state before pipe_buf_try_steal() in fuse_try_move_folio()
In fuse_try_move_folio(), check that the pipe buffer's folio is not
hugetlb, swap-backed, or already mapped/anon before attempting
pipe_buf_try_steal() and inserting it into the FUSE inode's page cache,
preventing VM_BUG_ON_FOLIO() and page cache state corruption.
