generic: test fsync new file after removing hard link

Browse Source 
Test that if we have a file with two hard links in the same parent
directory, then remove of the links, create a new file in the same
parent directory and with the name of the link removed, fsync the new
file and have a power loss, mounting the filesystem succeeds.

This test is motivated by a bug found in btrfs, which is fixed by
the linux kernel patch titled:

  "Btrfs: fix log replay failure after unlink and link combination"
