NFSv4 introduce max_connect mount options
This option will control up to how many xprts can the client
establish to the server with a distinct address (that means
nconnect connections are not counted towards this new limit).
This patch is setting up nfs structures to keeep track of the
max_connect limit (does not enforce it).
The default value is kept at 1 so that no current mounts that
don't want any additional connections would be effected. The
maximum value is set at 16.
Mounts to DS are not limited to default value of 1 but instead
set to the maximum default value of 16 (NFS_MAX_TRANSPORTS).
