ntfs: wait for the bitmap scan before MFT bitmap extension

If MFT bitmap extension fails before the initial $Bitmap scan completes,
rollback calls ntfs_bitmap_clear_bit(), which holds a folio lock while
ntfs_set_lcn_empty_bits() waits for the scan. The scanner deadlocks if it
still needs that folio.

Wait for the initial scan before taking the runlist or bitmap folio locks
and attempting allocation.
