nfs mounts must not be sync

Browse source 
This is a 10x performance hit.

It is reasonable to mount NFS in async. Just like with locally mounted
disk, there is a risk of data loss. But since it honors requests to
sync, the application is in control of when it matters. An
application (database, git, forgejo even) would have a bad design if,
for instance, it returned success on a write operation without issuing
a sync.
