Test that if we fsync a file with prealloc extents that start before and
after the file's size, we don't end up with missing parts of the extents
and implicit file holes after a power failure. Test both without and with
the NO_HOLES feature.
It is fixed commit f135cea30de5 ("btrfs: fix partial loss of
prealloc extent past i_size after fsync")
