commit 9597152d98 upstream.
This reverts commit c6eb58435b.
If a transport is down, then we want to fail over to other transports if
they are listed in the GETDEVICEINFO reply.
Fixes: c6eb58435b ("pNFS: nfs3_set_ds_client should set NFS_CS_NOPING")

Split out from commit "NFS: Add fs_context support."
This patch adds additional refactoring for the conversion of NFS to use
fs_context, namely:
(*) Merge nfs_mount_info and nfs_clone_mount into nfs_fs_context.
nfs_clone_mount has had several fields removed, and nfs_mount_info
has been removed altogether.
(*) Various functions now take an fs_context as an argument instead
of nfs_mount_info, nfs_fs_context, etc.

If a NFSv3 server is being used as both a DS and as a regular NFSv3 server,
we may want to keep the IO traffic on a separate TCP connection, since
it will typically have very different timeout characteristics.
This patch therefore sets up a flag to separate the two modes of operation
for the nfs_client.

Connecting to the DS is a non-interactive, asynchronous task, so there is
no reason to fire up an extra RPC null ping in order to ensure that the
server is up.

If the user specifies -onconnect=<number> mount option, and the transport
protocol is TCP, then set up <number> connections to the pNFS data server
as well. The connections will all go to the same IP address.

The flexfiles layout wants to create DS connection over NFSv3.
Add nfs3_set_ds_client to allow that to happen.

v2 and v4 don't use it, so I create two new nfs_rpc_ops functions to
initialize the ACL client only when we are using v3.
