[pve-devel] [PATCH storage] fix #3348: Revert "NFS: avoid using obsolete rpcinfo option"

[Fabian Ebner <f.ebner@proxmox.com>]

This reverts commit 816dadb17f8e28d7a0a092c055c0c07b6038e64c.

With '-T' one needs to specify either 'tcp' or 'tcp6', and using 'tcp' doesn't
work for an IPv6-only server. Simply switch back to using '-t', because $server
might also just be a host name, so it's not really worth adding extra code (and
calls) to figure out if it's IPv4 or IPv6 beforehand.

If preferred, I can send an alternative using
    rpcinfo -l $server nfs 4
but that requires parsing the output.
