This reverts part of ansible commit 72023d7462e78635264fd12bfdb23894b4163cba.
The immediate reason is that it breaks mounts where src is not a path.
Examples of such mounts are network-based filesystems such as nfs, cifs,
glusterfs, ceph, virtual filesystems such as tmpfs or overlayfs, and
also UUID-based mounts. It is too hard to come with an exhaustive list,
especially if we take non-Linux systems into account, so don't even try.
Additionally, it did not really fix the issue (ansible/ansible#59183) that
it intended to fix, because the mount could fail but leave a non-working
fstab entry for reasons other than non-existing src path.
